Of out bounds/GraalEngine Error?

[DarkFireXZ3]

I came on Graal 4 onto Graal Kingdoms and it gave me a GraalEngine.dll error first then it went away i opened a mass pm and then it closed the pm opened it back up then it froze up and completly went nuts and started causing me PC problems i'm not sure what exactly happened it's under control now it's just strange that it happened. Everything was fine before i got on Graal Kingdoms. I'm gonna make another post for some reason i can't attach i'm gonna reboot and try.
