[Casper] error message using Casper Remote after upgrading to v6

[Jeff Johnson]

I upgraded to v6 last week - seemed relatively painless and problem-free. 

However, when I tried to use the new Casper Remote for the first time
today, I got this error message:

Sending Wake On LAN command...

No matter what dmg file I try to deploy, I get the same error message
("Error: The downloaded package could not be verified.). All of these DMGs
were successfully deployed prior to the upgrade. 

Any insights from the JAMF universe?

Thanks
