Well I don't know what happen exactly but I think its about the mix-up that I made with 1 model... it didn't had at the time the DDS map... so.. it had a jpg.. and from then... all the time I try to insert a new model. He is looking for a file that I deleted long ago.. and doesn't exist. But I deleted all files and all the models , jpg , impcfg , matlib , objdef and he still can't pass over that file no matter what new file I give him. Its like I need a reset button so he can see clearly that nothing exists.
