Should I Re-Install FSX

Well I have downloaded a bunch of planes but the VC's are blacked out and there seems to be no fix for the problem. I am currently using FSX SP2 which I patched FSX to after installing it for the first time (After installing SP1).
Anyways, is there any chance that a re-install might fix my VC problems? Also should I install the planes into FSX without patching it to SP1 or SP2 first?
