I have a serious problem since updating DU 4.0.5 to 4.1.2; since then the engine is a) not working any more, but b) consuming all my capacity:

It's not possible to end the service or kill the process DUEngine.exe (even with admin priviliges), just a restart kills it.
I already tried to delete all my configuration in the registry, but - as you can see - it didn't help at all...
thx
