Hello @spaghetti_M, sorry to hear you have problems. This is a known issue, though. I think it might be fixed with the future updates of the Account system.
For those of you that are having trouble with login in to a forums.
Go to EDIT / Preferences
In a Privacy tab select "remove individual cookies.
And delete cookies for everything inovae related.
Go straight on to a forums click login (should redirect you back to main page, now that you deleted cookies)
Enter your login info and hit login. It will most likely not do a damn thing. Don’t worry it is just messing with you
Just close the login window and hit comunity button again. You should be loged in now.
