After the nightmarish attempt at installing P3DV4.5, and the associated frustration I experienced, I decided to reinstall P3DV4.4 fresh.  While I can get P3DV4.4 to run, (reduced FPS), I am not able to save a flight plan, or a Scenario.  I uninstalled Academic Client, and reinstalled it, but to no avail.  I can create the Flight Plan, but cannot save it to My Documents. I think I may have inadvertently deleted a file that I should have not. Does any body have any possible suggested fix????

Question that comes to mind is where did you install it to, if you installed it inot C:\ProgramFiles\ ect... for example it's probably a read/write issue.
