I'm using C4Pro which automatically installs TransPOser but I imagine this will be the same for you. There's a TransPoser preferences file called Preference.Txt which is located in a PoserImporter subfolder of the WindowsApplication DataEovia folder (depending on your version of Windows). This text file contains only this line: appP "C:Program FilesCurious LabsPoser 5poser.exe" on my system as I'm using the default location. Deleting the file will force C4 to remake it which may solve your problem. Or you might try editing the file if you think it needs it. Mark
