Version 2.69.3 Not Working

I recently changed the mapping plugin that I used from the product of a different company to your product “MapPress Maps for WordPress” version 2.69.2. I have been very pleased with the performance of version 2.69.2. However, your change from version 2.69.2 to version 2.69.3 has caused my map on both the user page and the Admin “MapPress, Map Library” page to go blank. Since I haven’t been using your product for very long, I am at a loss as to what is going on.
