3D blank on 1 project while working on other projects

[eeeehaw]

I recently downloaded SW v4.4 Full Install (with Java 1.6.0_45/32b) and successfully created a couple projects over the past several days that have been displaying, printing, and saving as PDF docs just fine.

Suddenly, I have one of those project files that (1) does not display/render the 3D image at all (the 3D window still exists but is blank), and (2) will not save as a PDF. It does, however, still display the floorplan correctly and allows changes to that floorplan. Closing SW and re-opening that project file does not recover correct behavior, while re-opening my other project file works well as desired. It appears that some type of corruption may have occurred to the non-working project file, but I cannot determine how to resolve the problem with that file.

Win7 Ultimate 32b with latest updates, Nvidia Ge510 with latest driver, 4GB system RAM, Java mem set to 600MB (default?)

If your project is on only one level, try to select all items in the plan and paste them in a new home. I'm not sure it will work but it's something you can try by yourself.
Otherwise, please send it to [url=mailto:[email protected]]me[/url], I'll investigate the problem on my side.
