Nemeth EC130 Black Windows in Rain! Please Help!

Hello there!

I have tried a lot of different approaches to this problem, none of them have worked! Whenever I fly the Nemeth EC130 in rain, the windows in the Virtual Cockpit are completely black. There is absolutely no view of the simulated world. I use P3D V4 and have played around with the settings but I still get solid black windows when in rain in the EC130. This problem only occurs with the 130.

Any suggestions welcome!

In addition I have tried to reinstall the 130 numerous times but still have the same problem.

Thanks!
