I just tried that and it worked. It is very concerning, however, that I have to do this awkward procedure (because I have to reboot). Was the integrity of the software compromised and how did this happen? I think Groupy is an amazing app because it is so useful. But if I have to purge and reinstall every few weeks, it diminishes its usefulness. I think the code needs to be improved to prevent this from happening in the future.
