Lightroom 6 Serial No Issue

[MarkR1961]

I purchased LR6 on 24th May 2017 from Amazon.  When I now open the software I get the folloing screen. (I've hidden the serial no for obvious reason) Has my serial No been comprimised? I only have it installed on one computer.

It means that the software thinks you have Lightroom 6 activated on two computers, you can't activate it on a third. Contact Adobe Live Chat and they can resolve this for you.

I'll do that, thanks for a prompt reply.
