Well.. I had this problem before, so I bought a new HD.. after some times I started to get the same message and I can find a real solution for that! That is the case... I have a P4 2.0, 512 RAM, geforce 64MB, 80GB HD and its parted in 3... C drive has 10GB free, D drive has 22GB free and heres where poser is installed.. and E 500MB free just for backup. I am using windows 2000 Now Poser started to give me the same message all over again. To be able to render 4000 pixel images I have to defrag and free space in C and D... after 2 renders the probem starts again... There must be something I can do...but what? Oh.. I tries the curious labs fix for the page file.. now .. what? I would be thankful for any help!
