A plugin you have installed is preventing the plugin from reaching the license verification server. We've seen this before with the "124thATC" plugin. Try removing that and seeing if the plane then activates correctly.
They already did. I believe right now its the FMOD sound, maybe some other things, the FMS to XP12 data conversion and update is going to be a while due to the- amount of work. Im sure they will let us know when they are ready. Its still good as is.
