Sorry if this is the wrong place post and if it is a little long but I'd like to know what I am doing wrong.

Long story short: I have been playing this game for the first time and I realized my choices of leveling up not only of my own PC but NPCs as well are full of mistakes from feats to abilities.. As this point I really don't want to go back and start from the beginning.. So I decided that Nexus UnityMod Manager with Toy Box to correct and not to make my characters OP. Anyway the UMM refuses to accept the Tou Box Zip File.

1. My game has the latest patch.
2. I followed step by step instructions from Nexus on how to install to the desktop.
3. UMM is the latest version.
4. Toy Box is the latest version and at the bottom of the first screen it says Installation is successful.
5.I then go to the Mod screen and it says (Toy Box) status is OK 5. But no matter what I do it will not install the mod. It wants a file and I get to the Pathfinder Folder but I am told every time that the ile is invalid.
6. I've tried several different times.

Under the Log tab I get this: [7:11 PM] Game changed to 'Pathfinder: Wrath of the Righteous'.
[7:11 PM] Game path 'E:\Program Files (x86)\GalaxyClient\Games\Pathfinder Wrath of the Righteous'.
[7:11 PM] Checking for updates.
[7:11 PM] No updates.

Your help will be appreciated. Thanks.
