Hello, is there anyone out there who has seen any of these problems, if so please, let me know I would apreciate an suggestions. I have had several project files become corrupted. One problem is that when I load a project file it says "invalid project file" and then it loads the file but some of the geometry is missing. (this has happened a couple of times lately and it is a BIG problem). Another bug that happens more frequently is that there are several project files the have a display problem connected with then. If I load one of these files then I can't display an image file in the editor or in the materials editor, but I can render an image and strangely enough, after I render an image then I can view other image files. I have tried re-saving the project files with different names and just saving off single meshes and merging into a new project, the display bug stays with any and all of the geometry. It stays with the file when it is loaded on another computer also. A third problem is that on some of those files it has affected the display of the images used as texture maps when viewed in the materials editor, they look like they are being viewed at 256 colors, at the same time I can load other images in the materials editor that look just fine.
