I keep getting this message, and the HUD stopped working
Merge: Unable to import hand (#5744389500600). Reason: Invalid limit (/0/6//2012 (6 max)) for hand #5744389500600

I've read through some other people w/merge problems,

I've downloaded the latest version, this happened just since their software updates.

You will need to update to v3.13.7 Beta which works with the new Merge software.
Scroll down the Download page to find the Beta version.
Make sure that PT3 is not running when you install the update so that the files can be overwritten.
