Thank you so much for your help. I am still stuck. I tried what you suggested; unfortunately the check found no errors, and running the repair didn't help.

I use the desktop for Mac version (not the online version). The bookkeeper is the one who works on the QB (I never touch it except to send files off at tax time). When I open the QB program, the only version of the company I can find is from 2015. I can't seem to open any of the files on My Passport, where all the backups are supposed to be stored. They seem to be formatted for the QB server and won't open. Supposedly the bookkeeper also saved the files on my computer but none of those will open either. Arghh! I am unable to open QB "preferences" (it is grayed out) to see where the heck else files might be. I am hoping there is some way to find and restore these files. Thanks!
