xxxx.pt# and xxxx.pts are files made in compiling by the compiling tools. Usually when you get "can't find .pts" it means something went wrong with compile. It could be a bad setup you made for the compile, or you're Running WC/hammer through normal instead of expert, or having "too many wads", or corrupted compiling tools (rare but happens), a bad path/name somewhere, or several others. The solution is generally to use a front end or batch file with zoner's compile tools, then the problem usually goes away or the compiling error becomes clear.
