If you dont know what a full wipe is, then stop what you are doing and put your phone down. Just about every rom thread here on xda explains what a full wipe is, it will be in the first post of the thread.
Like I said, find a rom you like in the t-999 section and flash it after doing a full wipe.

Looked it up, that is what I do by default, didn't know thats what was considered a full wipe, just tried it with similar results, didn't know about the dalvik cache though. im on a work computer so I cannot currently DL a new rom from the site, I hope thats what the issue is, but I still cannot see why my other ones would suddenly not work.
