Installing v.10 knocked-out my v.8 registration

I just installed v.10, but now v.8 (which I am still using for practical work) tells me I have an evaluation copy. And it won't accept my registration number.

Maybe its because I had v.10 running when I loaded v.8.

Only 8 "trials" left, so hope you can help soon.

I am not sure v10 caused it.

I am not sure v10 caused it. Please email me your "machine ID" by going to the "Help | About" window in Biblisocape 8. I can generate a new key for you.

Thanks for getting me squared away. All fixed now.
