The thing is, Im just geting tired of the same old ugly skins that I currently have on, and I want them to be default again, but im having trouble geting there.....

I've tried deleting it, and replacing it with another bitmaps.map file that I know dosent have skins. I start up halo, it works. I close it down, and start it back up, and guess what? they're back.
I've tried uninstalling, same thing happens.
I've tried geting the original skins in a .dds file, but so far I wasent able to find any.
Any help here would be appreshiated.
My system specs: Windows Vista Home Premium, Intel Core 2 Duo 1.86 GHz Each, nVidia Gefore 8800 GT w/ latest drivers installed.
