Update for Winamax Users
It seems Winamax has just released version 2 of their Mac software. Congratulations Winamax team.
The new version seems to fix an issue with dates and times in their hand history files. Poker Copilot expects this to be wrong, depending on your timezone, so has been autocorrecting it. Unfortunately as of the new Winamax update, Poker Copilot is auto-miscorrecting it.
Here is an unreleased update which you can download if this problem is affecting you.
Please do write in the comments whether this update fixes the issue for you.
