Reinstalled Captivate 8 does not work

My Captivate 8 application suddenly stopped working (would not run), and showed the screen in Screendump 1 (attached). I uninstalled and the reinstalled Captivate 8, but the same thing happens whwn I try to run the application.

When I clicked the link to Customer Support, the screen in Screendump 2 came up. The referred serial number on the screen does not match the serial number I entered during the reinstallation.

My Captivate 8 serial number as entered at reinstall: [ removed by moderator ]

Urgent - how to solve this?
