Ok here it goes... granted i'm new to this plane and all of its amazing features, i do have one question for now. I would like to ask if anyone knows how to save the co routes on the cdu. I have loaded the route with all the waypoints and sids and stars with all my weights and fuel. I pressed the save key on the route page but the confirm button is highlighted along with the exec button. but the cdu will not neither confirm or exec.

As far as your issue goes, it's an admin rights issue, most likely.

To do this, navigate to the Microsoft Games folder on your drive and:

Right click on the Flight Simulator X folder:

Select Properties

Select the Security tab at the top

Click on the Users account in the Group box

In the Permissions box, check the box Full Control

Click OK

This grants you and the programs you use in that folder admin rights to the folder. Essentially, what is happening is the computer is writing the changes (your key assignments) to a 'ghost' (Compatibility Files) folder, which the PMDG Options panel ignores the next time you run it. Using admin rights writes those changes to the actual file, not a file in a 'ghost' folder. As a quick note, if you have problems with any other program (especially when it comes to settings not saving, etc), you should grant admin rights to the program's location first before trying other things. UAC has its place in Windows, but it ends up being a bear if you don't know how to keep it in check.

Or disable that damn UAC once and for all. Then you'll have no more problems like that.

that damn UAC was the problem and I greatly appreciate your help
