Did you try logging on with local system Admin rights instead? I would recommend setting your server to start without Blink, restart the system, and then uninstall it. Blink is very protective of its services (in efffort to protect itself from something malicious stopping it) therefor sometimes completely starting your system without it running sometimes solves these types of issues.
Since your using Blink Professional, you are entitled to support via your own customer support portal located here:

Support throught the portal is a lot quicker than through these forums.
