Frozen at startup after a crash.

I hope someone can help me out because i'm starting getting quite pissed over this fiasco. I been playing for some hours and then an error popped up and the game crashed. Now, everytime i try to startup the client, it just freezes. Anyone else got the same problem or i can just add this to the list? Thanks in advance.

i get server issues like missions taking a minutes to load up a mission and sometimes when I hit an enemy it'll register seconds later
