Actually it is Link, LNK, or a shortcut (Windows calls them that internally, you don't normally see the extension) I'm sure. But after saying that I wouldn't know how to fix it, I'd suggest re-installing Poser for step 1 (over top of the existing copy), for step 2 try uninstalling (back up your data!)and reinstalling, step 3 might be going in the dreaded RESEDIT and try to find the referenes. An alternate plan might be just install a new copy in C:Poser 4, assuming the old copy is in C:program fileswhateverwhatever, and keep the old copy as a spare. Your new compter probably has a huge drive, Poser doesn't take up much space, I've got 3 copies myself.
