ReSharper Settings Grayed Out
===

Today I tried to made "Code Cleanup" of single file in ReSharper 6.0 (VS 2010). The Code Cleanup dialog did not show up so I tried again.

I then discovered, that the feature is grayed out and when I press hotkey for Code Cleanup, the notification area shows that the "command is not available at the moment".

Even the Code Cleanup settings are hidden. The panel where settings should be shown says that the settings are solution-specific and thus a solution needs to be opened (although it is, however).

All other solution-specific settings and features work, except for Code Cleanup.

I want to avoid re-installing ReSharper or resetting its settings, because otherwise I would need to set it up again (long and annoying work of setting all the options as before re-install).

I am afraid that backing up settings and restoring it again restores the problem as well.

Any suggestions?
