Hello

I'm having this issue with crashing in arenas every single game. It's funny becaue it's only when i play with a DK that i crash and it's not all the time. Some days i would be able to play a whole day with a DK without crashing and other days, i would crash every single game. But on those days i get crashes all the time, i could change the partner to for example a paladin, and no crashes would appear.
recently i noticed a crash where my oponent was a deathknight..
It's a error code #132 and i've tried the things listed in this forum, but nothing seems to work

Has anyone else experienced something similar? or does anyone have any ideas for what i could do to fix this?
