Ok, not knowing whether you are running pc or mac, here is a possibility. The new exe for pc directs the files towards the curious labs version of poser. Now if it is the same way with the sit file for mac, you may be expanding them to the drive you installed poser on. Now.... If you are still not upgraded and are running poser as metacreations on a pc, those files have installed themselves in a folder created by the installer called curious labs in your program folder. If you just changed the curious labs to metacreations, the new version of poser4 has a space in the file name.(poser4 vs. poser 4) So you may have two poser 4 files on your program files. If Mac expands the same you may also have two files in the same folder. Just my experience with the new installer. They're there, you just may have to find them.
