PMDG 777 conflicting with PMDG 737NGX

Hi

Every time I install the PMDG 777 I am unable to align the INS in the PMDG 737. I have pasted below the only post in a thread that I just opened detailing the situation.

"Hi

I have been trouble shooting  the three problems listed below that I have had since installing the 777.

1. Test equipment appearing when not chosen as an option in the FMC.

2. Ground equipment not appearing

2. Unable to align 737NGX IRS (not typing error)

Last night I did a system restore back to the point just before I installed the 777. This fixed problem 3. I then reinstalled the 777 and problem 1 and 2 were fixed.

Tonight I decided to do a flight with the 777. I loaded the 777 and everything was fine. I selected the short turn around state and again everything was fine. I connected ground power and turned of the APU and saved that state. On looking outside the plane I noticed that problems 1 and 2 had reappeared. I then decided to again do a system restore as my computer had also installed a windows critical update. The update was installed last night just before the 777 so on reflection I doubt that was the cause of the problem. I then remembered that I saved a panel state when I first loaded the 777. Therefore am wondering if my problems are caused when I save panel states?

I shall reinstall the 777 later but I need a "quick PMDG fix" so am going to downsize and fly the 737-600 first. 

I am using Windows 64 bit and I have FSX installed as follows: C:\FSX

Therefore am wondering if am right in assuming that saving panel states is causing my problem? To this end I will try again tomorrow and resist the urge to save."

I have now reinstalled but not activated the 777 and have tried to fly the NGX. Before I reinstalled the 777 I loaded the NGX and was able to align the INS in the NGX following the reinstall I was unable to align the INS. I even tried the instant align option with no success.

I have now spent over five hours trying to sort this out and would be grateful for any help. Whilst I have enjoyed my two flights in the 777 I certainly don't want to be left with problems with the NGX. The only thing I have installed since my last successful  NGX flight was the 777.
