I have an andengine program that works on one development machine but not another?
<p>For reasons with which I won't bore you, I have to change development computers, and for the life of me I can't get my project to work on the second machine.</p>

<p>I have one library which is a .jar file which both machine have access to. But the program works fine on machine A but on machine B I get the errors below. At first I thought check the manifest, but, exactly the same project works fine on Machine A. So it must be something wrong with my development environment on B. Right? I can't think what it might be. I've got more apis on B than A.</p>
