OH NO!!! Hope you don't have to pull your hair out, agent11

Here are possibilities: you have something else running, or your internet or computer or hardware may have problems. It's probably software, since gameguard has the error and is causing it to crash.

Try deleting your gameguard folder and close all applications, including anti-virus and firewalls.
