Plugin License Reset

Hi,

I'm trying to get a demo license for the SSL Duende Channelstrip working and after some trial and error it's working fine on my system in Reaper but Logic still gives a 'No License Found' message. Ist it possible to delete a preference file or something like that so Logic will acknowledge the license? I tried repairing the preferences using disc utility but it didn't work. I'm using Logic 9 and 10.8.5.
