Well this is what happens, if I get disconected or crash from server

I can never get in except by restarting my computer.
If i try after the disconection or crash, it says:
"Gameguard Error, Please try again after closing all programs that could colide with Gameguard or after a reboot." Then it comes up with [???]
I don't see the exe files anywhere, but I have set all the pictures of the SRO launchers on Windows 98/higher. Problem still occurs.
