system restore broke nav 2010

Windows 7

 

After doing a system restore I find NAV 2010 will not run. I had to turn off the anti tamper but it will not open so cannot turn it on. The only thing i can get is a really reduced rectangle with a reduce option in the left, a square in the middle, and an x at right. The middle square is greyed out. I have put  a screenshot , hope it uploads Ok

 

Edit no it will not post. It was a paint file
