That's unfortunate, i prepared the installer based on the sample you sent me, so that's the best i can do on my side. One thing, try installing the sample you sent me with this setup, if it decompresses fine then it's okay, but if it doesn't it has to be some Windows related problem, though i doubt it.

Side Notes : Gamer_2077, if by any chance you are reading this, i still have your problem in mind, it might take a while since i can't spare much time to computer nowadays.

Well the sample and the 1-2 Gigs file are decompressing just fine. That means SRep probably fucked up the bigger files. Hope i get them decompressed one day. :|

I forgot to update my finding here, but I managed to get my data back. All I needed was to use SRep 3.91B because I using 3.93A for decompressioin, I don't remember if I compressed my data with the newer one but the older version seemed to work without any problems. :)
