Alright i got some ideas that might work. Please backup your game first just copy the whole touchthegirl folder and back it up somewhere else.
First open the game Click Start Click on the gear or press p go to the second page > You'll see Data Management click on each of the orange dots and then shutdown the game. See if any errors come up. If they do shutdown the game and try reinstalling the costumes one at a time and then startup the game see if there's any errors.
None of that worked >
Alright just to see if it works try dropping this inside your touch the girl folder and overwrite all and then play the game.

You'll either need to extract first or drag and drop. Feel free to scan those files if you don't trust me. Still got an error? ok shutdown the game and try running each costume installer and then try playing the game now.
None of that worked either >
ok can you take a picture of inside your touch the girl folder like click on the folder and then press alt prtsc on your keyboard and then attach the picture here.
Last but not least >
I may have to upload my copy along with the settings as a last resort and hope that works.
