Okay, don't know if this will help on the insufficient disk space prob or not, but it did for me. I run Poser on Win2k in a seperate partition than my pagefile. I added a pagefile to the same partition I have Poser installed and now I do not get this error. From what I have been told, Poser expects to find the swap/page file in the same drive/partition as Poser. Can not say if this is true or not, only that it seemed to work making it so.
