Saved Models

I did like Tom Z said and saved the five models I was working on because I knew I would lose them while trying to get the colored skin to work. Well I did so I put the 5 saved files back into the models where the 30 models are in the folder but cannot get them to work. Have I done something wrong? Here is a snip of them,I also opened one to see that they were not empty and there is the model I was making so they were saved.

Thanks for nothing guys I figured it out. But lost all my icons,noone said I needed to back them up too.

You need to rename the Model1 (2). The transmitter will not read it.
All the models names have to be named like model1 and so on and need to be named in order. Ex: model1, model2, model3, model4
You don't want to skip any numbers in order. Ex: model1, model3, model4, model6
