Please restart PokerTracker 4 using the logging enabled link on your Windows Start Menu, try the restore once more from the root of C:\ again but remove all check marks under 'Optional' and see if that works. If the restore fails again then attach your log file to a
Support Ticket:
C:\Users\{Windows Login}\AppData\Local\PokerTracker 4\Logs\PokerTracker4.log
You can access the 'Logs' folder with the log file by clicking 'File --> Open User Data Folder' in the main PokerTracker 4 window and the file we need is the text file called 'PokerTracker4' or 'PokerTracker4.log' that is in that folder. In addition to the log file open the backup zip file and copy (don't move/remove) TOC.xml to C:. Rename C:\TOC.xml to C:\TOC.txt and attach that to the ticket as well.
