Please restart PT4 using the logging enabled link on your Start Menu, reproduce this problem and then report it via our support system with the log file - that will help us figure out what is going on here and get it fixed for you. You can find that file by clicking File --> Show User Data Folder in the main PT4 window - the file we need is the text file called PokerTracker4 that is in that folder.
The pre-release 4.11.10 and the final 4.11.10 are not the same. If you use OS X and are having trouble you should redownload 4.11.10 from our download page and run the installer again. The changes are particularly important for you and may fix your problems.
