I downloaded that 7-Zip program I'll see if that was the problem, being that my WinRaR might be on the ancient side.

Whenever I try to open any compatible file, such as .ter and .sur files for Terragen, an error comes up: "File is not compatible with this version." Or "Version file number doesn't match." I get the second error, on both terragen and Mojoworld. For Mojoworld its the planet files, moon files, and sometimes landscape files. I never ever get those errors with Bryce.

Those problems listed above isn't just from this site, I get it from other sites as well. I don't know why its happening on this computer more than my old one. With my old one, sometimes the file itself was corrupted, and fixing it was just to download it from another place. I can't do that with this computer, either the person changed the name, or whoever had the download removed it. Or my computer just hates me.

Um I'm not talking about MY uploads, I am talking about having troubles with downloading OTHER's freebie stuff. It's their files that are coming up corrupted in my program files.
