Good you're asking, since I do have a problem running Poser on W2k, although I don't know, whether the issue is related to W2k. I was about to send a question to Curious Labs, but might post it here as well. Here it goes: "Upon starting up Poser 4.03, after waiting for about 2 Minutes, I am getting the following error messages: Error in Plugin FF3DMF.ARP Error in Plugin FF3DS.ARP Error in Plugin ffdxf.ARP Error in Plugin FFOBJ.ARP Error in Plugin FFText.ARP I have re-installed Poser from the CD, updated with the 4.03-patch, but the problem did not dissapear. Given the plugin errors, I cannot load 3DS-, OBJ-, DXF- or DMF-files. Poser greys out all sorts of menu-items and becomes unusable until I restart the application. My system setup is as follows: Harddisk #1 (40GB): C: --> Windows 98 on a 4GB partition, reserved for video editing, containing Fast DV-Master and Ulead Mediastudio Pro 6.0 D: --> Windows 2000 on the remaining 36GB for all other applications, including Poser on: D:Poserposer.exe, and all associated files (Runtime, etc) Harddisk#2 (40GB) E: reserved for video and sound files (.avi; .wav; and the like) Any idea on how to get rid of the plugin-errors and how to get them working again?"
