Problem with the settings

Hello,
im playing Crossfire for 5 years now. I never had Problems with the settings. No that Crossfire moved together with Z8games i got folliwng Problems:
1. When i want to change the settings, my game crashes all the time after i click on the "save" button.I need to restart the game like 5 times, just to change one setting.
2. I was used to a wide resolution. If I use any resoltuion that is "wide" or 1200x800, everything looks like im used to, except everything is pixelated ( it's unplayable). If I use the other resolutions, its not pixelated, but the resolution is kinda weird ( sometimes the words on the left are as big as half of the screen).
Anyone else had this problem and can maybe help me?
Excuse my bad english, I had no clue how to explain my problem.
Thanks in advance
