i cant play arena like this. Anyone else have this problem?
Any fix or something i can try?
Already deleted gameguard folder once.

And this isnt my only problem, i also get random crashes outside of arena, but then the game just force closes with an ncsoft error report. in arena i get "not responding".

I thought the game was out of beta already :/

EDIT: This is what i am getting just now again in the second round of arena (but this error also happens outside of arena) :
