I've just installed another 5970 in my gig, after messing up with AMD catalyst + Crossfiring (Enable/disable) etc, my 2 cards are mining fine with phoenix miner ( deepbit.net pool). However, my bitcoin client is stuffed up somehow when I try to start the program, you can see the symptoms here:

The error popups in top to bottom order



I've tried to re-install bitcoin with the latest version but does not help, still can not access to bitcoin, and please note that I did not touch bitcoin during the installation of my new hd 5970.

Please give me some help, thanks !
