FSXA

Greeting all,I have been blighted by a series of problem with my PC, to cut things short my C hard drive failed 300Gib after 4yrs but since I renewed my hard drive I had to clean my D hard drive a complete format, this drive contained my hobby FSXA.OK I have FSXA back on my D drive all is well until now I have SDK Sp2 installed some of my aircraft the bell helicopter etc a invisible just shows the pilot in the cockpit NOTHING ELSE another example a FSX AH-64 attack helicopter all I can see is a bit of the main rotor and tail rotor, another aircraft in select aircraft the cockpit is functional an outside view nothing only the wing light.This is a weird thing to happen my original FSXA worked well until it got scrubbed, I would really appreciate some help please to address this.Thank you,Dave. Hi since the above I have deleted all SDK files etc, I started back with the basic FSX SDK, once in I switched off/On my computer again with SDK 1a and FSXA SDK currently nothing on my FSXA has changed, I'm toying with the idea of putting back SDK Sp2.Why did I did this this was one of the recommend options as well as delete fsx.cfg and switch of Aircraft shadows not much has worked.
