Problem with the Tmnt 2012 model

Hey guys, for some reason, my tmnt 2012 model isn't working, and it can't generate images, there is a message saying that it should fix itself over time, but it hasn't been several hours. I'll try to upload the file to a new version and see if it works. The same thing happened with the Makunga model.

I'll let you know when the model is working.
