well guys, i got my answer: there is no solution for me, it was my mistake, so i play for ever as cleric.
sounds fair to me.
don't delete ur class transfer marks kids, or u'll end up just like me.
guys if anybody is frieends with the gms pls tell them about my issue, i wrote to support 1 week ago, but i must still be on the waiting list or smth.
im curently lvl 54 cleric
still got this problem, alt+enter solve it for 5 days after it came back.
i also changed sound quality from 24 to 16 bits, disabled all sound enchantments
if any have any idea, throw fire away
