When I re-opened my project file, the calculations were gone. What should I do?

One user reported this problem after upgrading to Prism 3.02 and opening files made in version 3.01. We don't know why the calculations were lost--Prism omits some results when storing a project file in the "compact" format, but it should restore those results as soon as the applicable sheets are accessed.

But there is an easy way to force Prism to recalculate: From the results sheet, click "Change... Analysis Parameters". Click "OK" from that dialog without changing anything. Prism will recompute the results and they should reappear.
