I tried looking it up and got a few different answers, but not knowing where to look or if they would even help I am now going to the experts....I hope

To correct the problem:
1. Right-Click on your desktop
2. Choose "Graphics Settings"
3. Once in the OpenGL configuration page go to "3D Settings".
4. Switch "Force S3TC Texture Compression" to "On".

CEP tilesets require both tileset hak 1 and 2.
IDK if i have both hak pack or where to look or how to get the one i am missing. and I tried looking in my graphics setting but i found nothing that said what number one told me to do.
