Usually there are several cases when you may see this picture:
- You have copied not all the key OTYE1-II4L7-V4PYG-OKLOI-N7HKU. There are should be 25 characters with 4 hyphens without spaces at the start and at the end.
- You are trying to activate Verifika 2.1 or an early version with a key valid only for Verifika 2.5 and later versions. Starting with Verfika 2.5 we have a new server, older versions simply do not know about the server. Solution will be installing a new version of Verifika (at least Verifika 2.5).
- Uninstall Verifika from your computer by using the Add/Remove Program feature in the Window's Control Panel.
- Run Verifika Cleaner (see link below).
