I am trying to get DMM plugin working on a fresh 3dsmax2010 64bit installation but I am having some trouble with the activation process or the plugin in general.

Everytime I am starting DMM from the tools menue it tells me:
"The DMM licencse could not be found or your demo license has expired. Would you like to launch the license utility?"
After launching and requesting a 30 trail license the plugin tells me that there is a purchased licence already installed. *?*
Then the DMM menue shows up and max crashes everytime after creating a DMM object out of polygon geometry.

Any ideas?
Best regards and thanks in advance
