Hi,
Sorry for late answer. I tried to sign in a same day as you sent the post and it worked without problem. But it seems Groundspeak has some trouble with servers on their side as menion wrote. Anyway if it happen again, please send the app logs with Preferences -> About -> Send feedback action and I will look on it.
