doesnt let me logout/in

I tried logging in with my facebook, saw that this account wasnt connected to Heatmap. No worries, ill just log out and relog with the correct accoun-…..

“Hello G[name],

This site is using heatmap with a license limited to a single user account.
We are pleased that you like heatmap and want more user accounts 🙂 please upgrade!”

Ok??!!! HOW do I log OUT? I can’t.

So now I can never use heatmap for some reason because it think im another person, while I just want to log OUT. But I cannot anywhere find a button to log out from it….useless until this is fixed
