Error running in Ktoolbar!

Im trying to run an game in Ktoolbar, the build is fine and the program is displayed on the emulator but when the i click on launch i keep getting the following error:

java.lang.ClassNotFoundException: TravellingGecko

at com.sun.midp.midlet.MIDletState.createMIDlet(+14)

at com.sun.midp.midlet.Selector.run(+22)

Is this something to do with an incorrect path name or some sort of syntax error i dont know and its bugging me!!! Any ideas
