At this point, you should open your properties file in a text editor and inspect it. Also good to inspect your database Per_Image and Per_Object tables, to look for anomalies. You can post the prop file here and we can take a look too. If you run CPA in a command/terminal window, you can inspect the output and paste it here, too. Any crash logs on your machine might help as well.
Things to look for, for example:
* Does CPA have access to the images? database tables?
* Are the number of channels and their names correct in the properties file?
* Do the columns "cell_x/y_loc" exist in the database?
These all should be ok, especially if ExportToDatabase is configured properly. But things can happen
