Activity Gen causes errors, I get missing rolling stock Options

[prr4ever]

I installed the template for East River District in the route. I then opened activity gen and created an activity, allowing AG to build my train. I folowed the manual and the video tutorial in doing this. This route has been running fine previously and, in fact, I checked it prior to installing the template. Whenever I try to start the route now I get multiple errors of missing rolling stock and MSTS closes. Yes, I do use Train Store but I am assuming that AG is not asking for anything stored and is drawing stock from what is unstored. However I am wondering if, since the template may use default stock ,does it call this stock even though it is stored? If so, how do I change the stock already defaulted in the template? I do have Activity Master but it will not open the route now, giving me an error of "Input past end of file encoutered while loading."

I want to instal a number of route templates but am using this one as a way of getting everything working prior to installing others.

Any help is appreciated.
