Fatal Error: Open GeeksToy-Betfair Account

[Maciel]

Hi!
I open geekstoy, log with my user account of betfair and then it opens a window with this message:
"Error message:
System.Exception: The application could not load your user profile. Please login again
em AGeeksToy.frmLogin.LoginCode()"

What I have to do to resolve this problem?
thanks
