I spent many hours on my project, saved it in various formats to insure that at least ONE would work (WMF, mp4, QuickTime, etc.) After trying both the Export option AND the Queue option for rendering, I closed the file and searched for the final output. To my disappointment, the mp4 did not render at all, the WMF rendered in a small screen, and did not capture the entire production (not all frames) in the final product and I don't see a Qtime format anywhere on my computer. THEN, I reopened the project and the first 1/2 of the frames have disappeared! WTF. Very disappointed.
