Cant Upload model

Hey so i was rigging a model and everything is fine with it, i just imported it into the TU workshop editor and everything was perfect aswell. But whenever i try to upload it, the system fires back with the lovely “Generic Steam Failure” so i am here wondering what is wrong with my model that it wont upload. When i hit retry it uploads without the model and comes up as 0.0mb of file space so it never loads. Can anyone help?
