The files are associated with uTorrent and are opening just fine, but uTorrent is claiming that they're not. The UAC is off. I have tried running as admin just in case, but it didn't change anything. The problem still remains.
No, I don't have FlashGet installed and I doubt that something's stealing my associations, because then version 1.8.5 would probably be affected as well, but it's not.
I've installed uTorrent 2.0 (build 17920) and now every time I start the application I get the following message: I didn't have this problem with version 1.8.5. I'm using Windows 7 Ultimate x86.
