"Offline" License Key Is Invalid

[D3]

Today most of my SnippetMaster installations are getting the 'Your Local "Offline" License Key Is Invalid' error.

These sites are spread across three different host machines but are all located at the same host.

Any ideas on how to fix it?  I'm starting to get complaints.

Thanks,
Dan

I'm not seeing any problems with any of the license database servers (there are three of them at different datacenter locations).

Can you send an email to henri@snippetmaster.com with a sample URL that isn't working?

Thanks!
