True Image stops server boot

Hello,
It is entirely possible that I overlook something, but I cannot really find my error and it is driving me nuts. Here is the situation:

I have a server that everytime I do a reboot stops with a blue acronis page till I manually click on "Yes, for the love of all that is holy, please friggin proceed, goddamnit!" (slight exaggeration). I just want to reboot, is that so hard? I do _not_ want to manually click the goddamn button every goddamn time. It is driving me bonkers. There is no CD in the tray.

So, can someone please tell me: how can I make this stupid Acronis Blocker disappear?

Very kind regards and thanks in advance!
