For those that were unable to add GameTrailers.com RSS to the My Apps section, this bug has been fixed. There was a version mismatch issue between the one in the app’s descriptor.xml and the repository’s index.xml.

If you are still unable to add GameTrailers.com RSS to My Apps, you may need to delete the net.internalserver.dir.gtrss folder from your Apps directory first. Your Apps directory can be find in…

Mac: ~/Library/Application Support/BOXEE/UserData/apps

Windows XP: C:\Documents and Settings\<windows username>\Application Data\BOXEE\userdata\apps

Windows Vista/7: C:\Users\<windows username>\AppData\Roaming\BOXEE\userdata\apps

Linux: ~/.boxee/UserData/apps

If you run into any other issues, please let me know!
