I am really sorry for the inconvenience!
It looks like Roaming Manager Package is a Visual Studio package. To be honest, I have no idea what is that package and what it should do.
We could have a look at your ActivityLog.
You could try to remove %localappdata%\Microsoft\VisualStudio\12.0\ComponentModelCache
if it is a MEF related issue, but that is a wild guess.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
