active FTX Central 2 error launcher

[Warrens31]

Hello, I've recently purchased FTX : HD Trees on you're website, the installation has been successfull but and then I installed FTX Central, I chose my FlightSim P3DV3 but when I launched FTX Central, an error pop in, on my screen : FTX Central has encountered an unrecoverable error : the invocation of the constructor on the type 'Orbx.FTXCentral.MainWindow [.....] The details have been saved to your desktop as ftxc_error_295.txt.

So the error says :

I've purchased this 20$ addon but I can't use it because of my unworking FTX Central, please I would like you to tell me want to do so I can fix that annoying problem.

thank you very much.
