SBT2 and Stino 3 install error

[jpillora]

I followed steps here #179 (comment) and it was working. Then when I restarted sublime, the menus were greyed out. Now when I tried to reinstall, it's still grey and I see

Exception in thread Thread-3:

I've encountered the same error. Does anyone have a solution?
