If it only happens after a couple mintes of playing then that doesn't sound like something that should happen. Please comment your MTA serial below, I've set comments to be auto hidden
Hi, you're wrong about not having played with cheats, as someone on your device did cheat (or attempt to) on MTA.
But, the ban was meant to have expired 6 March, and this issue is being looked into.
@amirkla rather than replying to an old thread I have moved your post into its own area.
If you were banned by a server then you'll need to appeal the ban with that server. If you were banned by MTA then you will need to wait for the ban to expire.
I have moved your thread into client support forum (note that the private bugs section has a different set of posting guidelines).
When you say that you have restarted your operating system, do you mean you rebooted it, or did you reinstall the operating system and wiped its files?
