Aircraft conversions

I have recently located an aircraft that I would love to test out and possibly use to fly as a high altitude, mach 3+ spy aircraft. My problem is that it is written for FS2004 and I only have FS2002 pro. My problems thus far are three:

1) The over-speed warning comes on at 5 knots.
2) The constant hydraulic annunciator light is on (preventing the brakes from working).
3) The constant vacuum annunciator light is on.

I am a real beginner when it comes to aircraft modification (I know how to modify the aircraft file and basic little things). Can someone give me some direction on this issue, please?

Can someone:

a) fix these small (I am guessing) issues?
b) tell me how to fix these issues?
or c) offer a suitable replacement for this (not a SR-71 or U-2, I want something more futuristic).

Thank you for your help!!!

I would suggest a email to him asking if he can alter the cfg. for you.
I'm sure he would be willing.
