Your app_info is from the team mod, it doesn't work with 6.6.*

V10 pack does work with any 6.6.x BOINC including 6.6.20. Actually I running it exactly with BOINC 6.6.20 right now.
But starting from BOINC 6.6.14 as was mentioned many times in this thread already there is possibility to use BOINC own scheduling mechanism for CUDA applications to run both CPU and GPU SETI MB versions simultaneously. That's why team pack can be disabled now.
But to do this you need replace app_info.xml _and_ SETI CPU MB "teamed" app ("teamed" AK_v8). Only SETI CUDA MB and SETI AP should be leaved untouched while upgrading from V10 pack to BOINC 6.6.20.
You need to delete cc_config.xml also (or just edit it to remove ncpus section if you use cc_config for some other purposes too).

What with 23 pages of app_info.xml postings, corrections, BOINC version x.y.z and a.b.c, it is more then just a bit confusing.
I wasn't running CUDA before. I just replaced a GPU that was failing and upgraded to a CUDA GPU. So there were no changes to be made to the cc_config.xml file.
In anticipation of the CUDA work, I upgraded from a 5.x BOINC to the latest version 6.6.20.
I used the ap_info.xml from the v10a package and basically only removed the AP information. After that, I just copied everything into the projects folder and started BOINC back up.
Exactly what other changes do I need to make to the app_info.xml?
If need be, I am willing to downgrade BOINC to 6.4.7.
Raistmer:
Downgrade not needed.
You can use first posted app_info from corresponding SETI forum thread (and more or less safely ignore all later 23 pages ;) ) but check if app names corresponding names of your executables.
That way you need unmodded AK_v8 (from download section of this site), my V10/11 CUDA MB build (from this thread) (I assume you don't want to run AP so not listed it).
Another way is install V10 pack as it is. Add cc_config file with ncpus field (look first page). For doing ONLY SETI MB on both CPU and GPU, w/o AP or other projects V10 pack seems to me as more preferable way (still) cause it can balance workload between CPU and GPU while BOINC has separate work fetch (you can have plenty of "CPU" MB tasks while your GPU will sit idle cause it can't fetch new work fot itself).
If you participate in some another project too then BOINC 6.6.20 preferable.

I have tried a few time to get this to work......
Each time I error out and loose some WU's.......
Could I get some help please????
This is the machine:
http://setiathome.berkeley.edu/show_host_detail.php?hostid=4293313
It's running Vista Ultimate 32bit, it has 2 8800GTS's 320mb, 182.50, Raistmer's_opt_pack_V10a_x86_SSE3_AMD_MB_CPU_GPU_team.rar, BOINC 6.6.20
Also, I am trying to just get Cuda to run on there, what I am looking for is a way to kill off VLAR WU's....
Thanks for your time...
Raistmer:
If you lose tasks it means you don't follow the rules for upgrading.
"
The recommended way to do any (not only this one) update of opt apps:
1) DISABLE network access in BOINC
2) STOP BOINC
3) Copy BOINC whole data directory in another place as backup.
4) install update
5) start BOINC.
6) if all work fine - resume network access, else - stop BOINC and restore BOINC data folder from backup.
In other case you risk to trash whole your cache and be blamed by all few hundreds of your wingmans for that unfriendly action!

app_version download error: couldn't get input files:

That means you don't have this file but you need it before downloading any work with app_info file installed.
Either edit app_info to point on CUDA MB app you really try to install or download this stock version first.
Slagathor:
I did the data folder back up, but even when I put it back it was gone, but anywase.
I got rid of the stock app, prolly shouldn't have, and I just copied the whole rar to the work folder.
The error you posted happined a bit ago, before I said ta hell with it and used the stock app again.
But, like before, like I said, I copied the contents of the rar to the work folder, I didnt change anything in the xml, and everything errors, even with an empty cache, then it downloads a couple WU's and them error out also....
