Help with Bootskin issues!!!

I installed the Bootskin software with no problems. I downloaded a few skins and installed them with no problems. My problem is that when my PC starts, the skin color is distorded and when it is passed it, it messes up my monitor's screen resolution. My monitor is a HD screen that needs to be set to a resolution of 1680x1050. Do I need to change the resolution of the bootskin? If so, how do I do it? Any other ideas. I'm new to this whole bootskin theme thing. Thank you!
