Ok, after I installed the scenery for the Hoffstadt Bluffs helipads, I began to run into problems with Flight Simulator.
It'll start up fine, and then right after you've selected your flight parameters (i.e. starting airport, aircraft type, weather and time of day), it'll load and then right when the cockpit view opens up, I get this error that forbids further play of FS9. it reads "FILE ERROR: Error Reading from File" with an OK button. Clicking this button closes out FS9 completely and it's been doing this for about a day now. Also, when it does this, some textures won't load on aircraft. In some instances, textures on't even load at all - interior or exterior. Could I have inadvertently screwed something up?
Even doing a system restore won't solve the problem.
