Yes, I tried to select them and click Next, but it doesn't do a thing and gives me a message, that I posted before, where it says "In selections you've checked don't need any changes to be made."
The thing is, that NoteCaddy itself is running. I can click on it and see Hand Reports, but there is no HUDs anymore: MTT-Edge or Cash-Edge, but I had them before... Do I need to download them from somewhere again?
That is strange, it sounds like you should try to reset your NoteCaddy settings back to default and see if that solves the issue.
1. Close PT4 and navigate to: C:\Users\[WindowsUsername]\AppData\Local\PokerTracker 4\Data\AppsData\Tm90ZUNhZGR5.
2. Make a backup of the .xml files (copy/move them somewhere else on your pc).
3. Delete the .xml files.
4. Restart PT4, go into NoteCaddy and set your settings as you prefer again (File → Settings).
5. Try to install the package(s) again via 'Manage my Ultimate Packs'.
Your HUDs should be located in a desktop folder named 'NoteCaddy Coaching Pack Files', but they won't do much good if you don't get the package installed into NoteCaddy first (they need the definitions for the HUD to work well).
