Losing drawings in Revit 2010 arch.

[mbracey]

I can create a new drawing in Revit, save it to a flash drive, move it to a different computer. When I do this I go to open my drawing and I can see it in the preview but when I open it the drawing is blank. Any ideas? Video Card problem?

What do you mean when you say that it's "blank"?  Are you saying that you're creating a new project file (.rvt) on your computer, drawing something, copying that file to a flash drive, then opening the file on the flash drive, and what you drew is no longer there?
