Hi Aaron, I know its two month since you have this problem but I came to the forum because yesterday I have the same problem. Do you solve it? How? The problem in my computer appeared when I try to render in 4090x4090 pixels and it told me that I have the disk full to render at that resolution, and when I exit Poser and enter again it has the problem. I have 3.5Gb and 8Gb in the other disk free. And before yesterday I can render at 4090x4090 pixels without a problem. I cant connect to the Internet because my ISP has a mayor problem. YESTERDAY WAS A VERY BAD DAY! I try everything, reinstaling an old Poser version, and the problem was still there, reinstalling Poser 4.03, and the problem was still there, reinstalling Poser Pro Pack and the problem was still there, uninstalling all Pro Pack and Poser, deleting the all the directories, restarting the computer, reinstalling everithing and.... the problem was still there. I reinstall windows 2000, and reinstall Poser and the problem was gone. :-) I lost all my afternoon. I was crazy, walkiing in my walls. I start rendering again, it cant render at 4090x4090, and the third time I try it it appeared your problem again. I was going CRAZY thinking if I have to reinstall all again. Before doing anything else, I delete some temporary files, in the folders Temp and Tmp in my root directory and in all the folders Temp and Tmp that I found in the "Documents and Settings" directory. I restart the computer and.... the problem was gone!!!!!! I still have the rendering problem, I cant render more than 1500x1500 pixels, I have 3.5Gb in C: and 8Gb in D: and Poser tells me that I dont have disk space to render at that resolution. Its not a memory problem I think, I have 800Mb memory free. Diego
