I have same problem. (instruction - You need to be on the screen in-game where you can see the values, for example for perks you need to be on the perk screen for money on the inventory etc. saving the game and loading the save will help as well. - not working.) Only Money,Weight and Skill Points available. Run as administrator, disable antivirus, run from game folder, SAVE/LOAD - no effect.
This problem was solved for me once I had a level up ingame and I had values everywhere.
fair but what I mean is, I have the same necessary set up for trainers and can still activate use and get past the splash screen of other trainers, it is simply this and I don't know how to rectify this scenario.
