MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
You don't have to guess... it's right there in the instructions that you need support for those. This is a very basic print job, you shouldn't be having problems with it unless your printer is performing poorly. You might also want to have a look at the derivatives.
