To make sure you have the correct version of Flash Player installed on your computer please download and install it from this link:
Download Adobe FlashSelect the correct version of the Windows operating system in Step 1 and then download "FP XX for Firefox" in Step 2. Once you've installed that version, restart PokerTracker 4 and you should be able to watch the in-client videos. The videos are also available to view in your web browser
here. If that doesn't get things going please
enable logging, reproduce this problem and then send your log file to us in a
Support Ticket. 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.
