I am having almost the same problem since installing the new CS 727 version 2.6. The 727 VC switches, etc are useless.
My other planes are fine so far including CS products.
Been working via support tickets with CS now x 2 days and still the VC is useless. Version 2.4 was OK.  CS support have been great so far with this issue. Hopefully will be able solve it this week

Did you ever get this issue resolved only i'm having the same problem. I have tried everything that has been suggested on other forums as well as this forum on multiple posts.

I have installed and repaired so many times, i have my security turned off when installing as well as making sure that i 'Run as Admin', but everytime i load the aircraft the gauges don't work none of them, on the normal models (non freight) there isn't any click spots appearing, on the freight models the click spots appear but you can't do anything with them the dials just don't work or turn.  The fuel panel is blank and none of the engineers panel work either.

This is really frustrating as i have this model on my other pc working in original FSX no probs and its a dream to fly i love it but it baffles me as to why it doesn't work on FSX SE????!!!!
