Hi! Ca. 1 month ago, my windows started to be very slow. To solve the problem I reinstalled my OS, but when I install MTA, and I tried to join a server, i got this message. (Attached pic) I never used any cheats or trainers, so this is very strange. Probably my serial changed. Can you help me with this? Thank you!
