I had the same problem too. I cleaned the project, updated the source code, close eclipse, restarted the machine... nothing. Then I took a look around the menu items in eclipse and found Project -> Blackberry -> Clean Simulator. I selected Blackberry JRE 5.0.0 (the only root option that I had) and pressed ok. After this, the simulator started successfully.

I think the problem happens because the BB JDE component package version does not match with your simulator. You would better switched to another component.
If you are using eclipse, download another JDE plug-in first and install it.
Then reconfig it by click blackberry->configure blackberry workspace ->blackberry JDE->Installed components. choose the new version
Well try another time if it works or not.
