If you can't exit the stealth mode, this might be due to an internal error of the application. In this matter, I strongly suggest that you use the USB stick that came with the program. This might be the only way to make the program run outside the stealth mode. If you still encounter difficulties in this matter, try to contact the developer using information found on the stick or under the Help menu. The official website of the developer is down, so you can't use that to reach the developer.
