MarketPress update issue in CoursePress PRO

Hello friends,

Last fall I was prompted to update databases for Market Press and was assured data would be backed up, I went ahead and was given the success prompt after a while. However, product pricing and currency disappeared afterward and I had to reenter values and reconfigure. Now, however, it seems people are unable to register new acounts in CoursePress as well as adding products to the cart. The screen hust hangs. See enclosed pic.

As always, I appreciate you prompt attention to the issues, and I thank you in advance for your help.
