This error is a bug in RMCTools. The dialog says the firmware is different, but the firmware is actually not different, and the dialog should not need to appear. The problem is that RMCTools incorrectly saved the firmware build date. We hope to fix this bug, but the problem may still exist in your project. If you send us the RMCTools project, we can try to fix it for you.
