Problem activation Toolbook 10

I have a problem which I hope you can help me with. I purchased Toolbook 10 on (data). I have recently updated my Windows operating system from Windows 7 to Windows 10 on both my computers. Unfortunately I did not realize that this would affect my Toolbook installation. I am now unable to use Toolbook at all as it is no longer activated. I cannot reactivate the software and cannot connect to your Toolbook site either. Could you help me please?
It seems that the activation site has been deleted. How do I reactivate my TB 10?
Thank you
