We've been running fine for a long time. Over the past weekend, our NAV consultants changed our NAV license because they had accidentally installed their DEV license.
Coincidently or not, suddenly JET Reports in Excel pops up "You are not licensed for this data source".
When I bring up the Application Settings and click license, I see connectors for NAV, GP, Jet Enterprise. The expiry date is "Does not expire".
Licensed version says 18.1 however when I bring up the About screen it says Jet Professional 2017 R2, 16.1.17033.0.
Any idea what could have caused this suddenly?
