We use Sage 50 Quantum Accounting.

For the last three or so days people have gotten daily pop-ups asking for them to activate.  "Product Activation, you only have 4 uses left.  You should activate your product soon."  The software has been activated for months, so why would this be showing up randomly?  No changes were made to the server, or version.  When we go through with the online activation it seems to work fine.  But the software was already activated, as you can see here:

Why would it prompt for activation when it is already activated?  

Thanks.
