QB Issue Resolution:

To perform the reboot.bat, just click the hyperlink and it will provide you the article to be followed. Sorry if I confuse you with the 1-3 steps. Upon checking, I agree its a bit confusing. Let me re-phrase it.

1. Hold down the CRTL key and open QB. This should open your company without any open windows.
2. If you require a password, enter the PW and click OK.
3. Hold the ALT key down until the company finishes opening, hopefully with no windows open.
