Doing these steps - in this order - finally worked for me.

1. Download & install the R6P update.

2. Run Verify Data. (File menu, then Utilities)

3. Rebuild Data. (File menu, then Utilities)

Note: Since I have my auto updates on, I assumed that the R6P patch would fix the issue. It did not. Once I completed ALL 3 STEPS in that order, my customized/memorized reports opened!
