Different Problems when going other Zones

The first one is "Bad Allocation" in the loading screen when going to another zone, and then the client crashes. Happened going to the Encampament from the first area of act 2.

The other one is
when going to Dark Forest from River Crossings



And after the two, appears the average Microsoft Visual C++ Runtime library Error

pd: I have played Closed Beta for 1 month and now this happens... ffs
pd2: I'm still having the dark forest problem... can't go into there :/
pd3: Ok I have changed video settings and now works... "-.-

Help pls
