I needed to change the drive for my fs9 from C to E due to lack of space. first i uninstalled all the pss packages and then the fs9. i reinstalled fs9 on e drive and then installed the fs9.1 patch. after that installed the PMDG 737NG on the new drive.i then did a reinstall of PSS A340 and PSS Airbus pro packages. i did not install the FSUIPC from the PSS site as it is an older version. PMDG installed a FSUIPC ver3.40 on my modules folder. i also changed my screen resolition from 1024*768 to 1280*1024*16mhzcolour. ever since i am having tons of probloms for the pss and have been virtually unable to fly the planes.A340 : during the flight programed to cruze at FL370 the aircraft would not go above FL340. moreover it then stopped responding to the autopilot for FL commands. for eg. when i asked it to decend to fl300 through the autopilot, it continued its decend to fl220. i had to manually pull the plane back up. is it an fsuipc problom?A320 : this has major probloms. in the 2d panel view mode, there is no sky or scenery in the window. it appears totally black. toggleing the view is fine but the problom persists in 2d view. moreover the 2d panel is not placed right in the opening screen and apprears moved towards the top. the bottom of the screen comes black.the load edit facility for the A320 also does not work.pls help.Dinkar

sorry i forgot to add :the PMDG planes work just fine. i have posted this on the PMDG forum so that anyone who has both the packages installed i.e. PMDG 737 and PSS Airbus will be able to understand my problem and help me better.Dinkar
