so should i try uninstalling fsx. would that help(hopefully)
Yes, it should probably work.
If you have addons with Uninstallers (like ours), it's best if you uninstall them all first.
Then, if you have FSX SP1, uninstall that one first, reboot, Uninstall FSX, reboot. Remove the FSX folder, if something is left, then you can start from scratch.
When reinstalling, don't install any addon, until you are finished with FSX + SP1 + SP2 and verifyed that everything is working.
