So I joined the Beta, but I have a slight problem..

I can play usually for a good 2-5 minutes, then it randomly crashes, saying ESO "unexpectingly crashes".. This happens everytime I log on and is getting quite annoying,

any advice?

Yes. You are not the only one having these types of problems with the game. They have serious stability problems. My advice would be to forget about beta until the devs get their act together. If enough people do not participate in beta the devs might get the idea that they should fix the game.

People have to read the beta notes: This is the same beta version as last time, no changes. This is in all reality a stability and stress test for the servers.

Never played last Beta, so thanks for your oh-so-helpful comment.
