When I attempt to download the Linux 32 bit AstroPulse_v5 - Transitional v5.00 (r103) & v5.03 SSE2 (r112) app I get the following error:
filesize() [function.filesize]: Stat failed for /home/simon/www.lunatics.at/downloads/ap500_503_linux_x32_sse2.tarHOLD.bz2 (errno=2 - No such file or directory)
I did manage to get the download in the end, but I had to pull out the HOLD part from the link provided.
