Hi Anna-sap,
The problem is most likely either that the LUA server did not successfully download those definitions, or that the SEPM can successfully downlaod them but is running into problems processing them.
As SebastianZ says, the log.liveupdarte from teh SEPM will tell a lot.
Also check the Event Logs on the LUA 2.x server: if that has had any download failures, there will be corresponding entries.
Please do keep this thread up-to-date with your progress!
