If your launcher has stopped working minimizes or otherwise screwed up here is the real fix.
Go to your start tab click and find all programs. Click on accessories. Click on system tools. Click on System restore. Select the last day that you know your system was functioning, then follow prompts.
This WILL reset your system to the last known working order. Then when you open the launcher go to options and select force verify. Yes this will be a slow patch but after this your launcher will work.
So to the DEVS who could not figure this out SHAME ON YOU !!!! This makes me wonder why you have a job if a techie simpleton like myself can solve the launcher problem and you the so called experts couldn't.
