Please restart PT4 using the Logging Enabled link on your Start Menu and reproduce this problem. Then please send us the PokerTracker4.log file via a support ticket so that we can investigate this further for you. You can find this file by clicking File -> Open User Data Folder in the main PT4 window. The file we need is the text file called PokerTracker that's in the folder that appears. That will contain the full text of the error message and we can use it to figure out what is the proper next step for you.
