I also just reinstalled 1.07 and no hands are showing up even though it's successful in importing.
They show just fine on the HUD.
One other thing that's worth noting is that when I click on change player and choose my player it shows 123 hands while the sessions/reports tab show 79. I think those 123 are all the hands I had played so it has them in but just not showing?
No filters or anything are on, it's pure fresh install.
