the other day i found these esf dragon ball z half-life mod models online, and when i downloaded them (and unziped the files) they were already in .mdl format.but when i tried to load one of the models into the med model editor, a message said there was an error loading the file! i dont know whats going on ive tried loading it into another 3d software, but it doesnt load in those either. is my version of med old? or is the file just corrupted? please help!
