Weird problem just happened. Downloaded a .rar file, opened with 7zip, said it couldn't be opened as an archive. Tried again, still nothing. Re-downloaded it, still didn't work. Installed WinRAR just to see and, surprise, that didn't work either. Downloaded a .7z a few moments later. When I tried to open it with 7zip it said it was corrupted. No luck with WinRAR either. Both were from the same source so I went to another website and downloaded a few .rar's. They were all either corrupted or "couldn't be opened as an archive". I've uninstalled 7zip and WinRAR and used CCleaner to clear out the temp files and registry and it still has not helped. This just started happening within the hour.
Anyone have any ideas?
