Licence problem

#1
I registered many months ago, but have since reformatted my hard drive.

I have re-installed progdvb and when I enter the key, it recognises me and tells me that the program is registered to me and I must restart the program. I do so and I need to enter the key again and I must restart and this happens over and over.
I cannot use the program because of this.

What must I do please to sort out this problem?

I am fairly sure I had the exact same problem when I very first registered.
