I have been having issues with FSUIPC ever since i have updated it to 4.939. I dont know if the version that i have is current or not because here in the forum i see 4.938e as a current version. I have this on FSX boxed edition by the way. My problem relates to the weather and the plane. I dont know and im not sure if its the weather or the plane thats causing the issue. When i take off using PMDG's T7 the problem is it does not climb. But when i go to fsuipc settings and set weather off the plane starts to climb. I dont know why it does that. Also on approach, even with vref +5 the plane is struggling to be stable and therefore it drops like a heavy iron. Before i updated my FSUIPC everything was working well. I have done numerous times of reinstalling FSX with no success and i even reformated my drives but the issue is still the same. I would appreciate your help. Thanks.
