ok, problem solved!
i started a new char and got in contact with a GM.
The last thing before the last crash i did was to rapidly type: /die
The GM told me i were in the drm. Ok, didnt know that. Now it seems to run properly.
This might be a solution for others.
So, it was NOT my computer. I guess a freezer with something, who knows.
so, im gonna test those pterosaurs now

cheers all
