Display problem

[smileyeagle1021 0]

I've had CitiesXL 2012 installed for several months with no problem.  Yesterady I installed a new graphics card and now every time I launch the game my monitor goes black then gets a message "cannot display video mode".  This is the only program I get that message on.  Is there anyway that anyone here knows that I can tweak the video settings from outside the game to try to get it to work? 

I already contacted CitiesXL tech support, and all they could suggest is trying to adjust my resolution on my desktop to try to get it to work, but that hasn't done anything.
