Hi Tut! Thanks very much for the advice, though it seems it got resolved on its own. Today I gave it a try and connected without problem and to my biggest happiness, without windows reinstall.
Funny thing was even when the ban was active I could join the other server of SeeMTA (Las Venturas) but not the main which was odd as this ban was probably supposed to block every server.
Anyways just wanted to give an update on being resolved on its own, could be that the false flag trigger dissappeared (my guess is a temp file maybe, or just something ran funny that AC didnt like. i know it might sound odd that I know about temp files, troubleshooting methods and auto flag triggers but not how to reinstall windows properly, guess its about time for me to lean how to lol, because it was embarassing even to admit it xD])
With that said I will go ahead and say we can close this question now(This was my first post on this forum so idk if moderator closes it or Im supposed to).
Thanks again and have a great week!
