I'm still testing with IDM 4.02 Bundle Edition on OES 11 SP1.

Now the first diver complained about required activation and refused to
load. In installed the BE Licence File and the "Activation required" message
disappeared from the Driver Set - but not from the drivers. The first
installed driver still refuses to load, newly installed drivers still show
"Activation required".

I searched the docu but did not find any information what I need to do -
what am I missing?
