Hey staronline,
Just checked our log for login attempts and I couldn't find any entries for your username or your email.
If you're trying to play the Private Demo (any version before 7.5.9 which is visible in the upper right or lower right corner of the login screen), Morningstar's right, it's an outdated build that we need to deprecate so we don't get false positive bug reports.
Let me know if it's the 7.9.5 version you're trying to access but still can't.
