I have 2 app versions - pro and lite. They are both already on the market at v1.01. I am trying to release v1.1 for both. This update includes SwawrmConnect integration i
I strongly suspect this is your problem
the reason being: when you add a library project to an Android project in Eclipse, it doesn't show up in your libs directory. I actually tried to add just the .jar file to a project and got told that that was the wrong approach (at least until API 14, I think).
My guess is, in your "non-pro" version you didn't link it in the project options and thus it still compiles correctly. Still, you should link it the way I just described to avoid problems when the library tries to access its own resources.
