Windows 7: 1024x768 gone (1024x600 availble) on HDMI, yesterday it worked?

1024x768 gone (1024x600 availble) on HDMI, yesterday it worked?

When I try to play a game called F-22 Total Air War 2.0 I get an error which says that the resolution 1024.768 is unsupported by the harware.. so I look into my desktop options and it looks like there is an option for 800x600, 1024x600, 1152x648 and higher wide screen resolutions but the 1024x768 is gone? I did play the game yezterday, I disconnected the HDMI, got upstairs, played a few more games, came back downstairs, plugged in the HDMI, launched the game and bam I got the error! I have a ATI Radeon Mobility HD5470 and the newest ATI Catalyst Center downloaded 3 days ago. How can I 'enable' the 1024x768 resolution again? Without it I can't play the game on my Big TV and I will be stuck with my little laptop screen.

Have you tried updating your graphic cards drivers to the latest version? Also what game is it?

Yes I Did, the game is F22-TAW 2.0. On other games the 1024x768 resolution won't work either anymore (Need for Speed Underground 2 keeps returning back to 800x600)
