1. Delete Windows Defender.
2. Open up Window's Search program.
3. Search for MSVCR80.dll
4. Delete those files
Those steps worked to get Graal up and running again, and I had to experiment considering the Graal help e-mail address is.. unactive?
Anyway, I haven't had any problems yet, but if you want an antispyware program, go to <http://www.safer-networking.org/en/mirrors/index.html> and find a good mirror for the file (which is called SpyBot, and it works pretty good). I also use Ad-Aware, so that is a good program too. Also, Zone Alarm seems to be a good firewall.
P.S. Don't blame me if the anti-virus/spyware programs don't work (for you), they are just suggestions.
