I use Vuze to download my torrents, i've never messed with utorrent. When MCM scans torrents on piratebay it finds a valid torrent but then displays the message: There was an error trying to save the .torrent file, verify that the path is configured correctly.
I've read multiple threads regarding this error and still cannot get mine resolved. I installed MCM on another computer and it downloads the torrents just fine but when i try on my main PC, it gives the error. Both pc's have the same settings.

Almost sounds like a permissions issue.

the troubleshooter doesn't show any issues with permissions

Things like this are hard to troubleshoot since you have already proven it is a issue isolated to that machine.

Have you tried uninstalling and reinstalling MCM? Since a new install on a new machine works.
