Hello,
Sorry to hear you are having issues. But, from what I see you can not start "Start11" if you not activated it. I tried, and it will ask you to Enter product key everytime I start the program. Strange, but you can try this and see the activation box popup.
Press the Windows key and "R" at the same time. A "Run" dialog box will pop up, please paste the path below into the "Open" field and press OK:
In the folder that pops up, you should see a folder named START11 (<-- the product that is giving you the error). Please delete this folder and all of its contents.
After you have deleted that folder, please attempt to activate it once again and it should succeed without any errors.
Thanks
