When using download studio with Filesonic, rar archives are always corrupt with bad crc errors. However when I download the same rar's just using the standard browser download function, the Rar's extract perfectly.

I have tried many different rar archives and in all cases, the download studio ones are corrupt from Filesonic, yet the standard browser downloads pulling the exact same files extract with no errors.
I have no problem with download studio rar's when pulling files from rapidshare, hotfile and megaupload - all come down and extract perfectly, it ONLY with Filesonic that this happens.

I have a premium account with Filesonic that I just purchased, so surprised I am seeing this when other file sharing sites work without this issue. Would add that both the rars from download studio and normal download process are the exact same size.

Hopefully someone here has experienced this and found a solution!
