Help: Package Load Failure

I had Resharper working fine in VS.Net 2005 for a few days, and then something got corrupted. I have uninstalled and reinstalled 2.5.377.0 and I get this message when VS.Net starts up:

-

Microsoft Visual Studio
-

Package Load Failure

Package 'Visual Studio Environment Menu Package' has failed to load properly ( GUID = {715F10EB-9E99-11D2-BFC2-00C04F990235} ). Please contact package vendor for assistance. Application restart is recommended, due to possible environment corruption. Would you like to disable loading this package in the future? You may use 'devenv /resetskippkgs' to re-enable package loading.

Yes No

and then, this message appears:

-

Microsoft Visual Studio
-

The Add-in 'ReSharper 2.5.337.0' failed to load or caused an exception.
Would you like to remove this Add-in?
If you choose yes, you will need to reinstall the Add-in to use it again.

Error Message: No such interface supported


Error number: 80004002

Yes No

Is there some way for me to manually register the app with VS.Net 2005?
