I have been out of the sim world for awhile so I apologize if this is a common question. I recently installed sp3 and within the WX CONFIG screen, if I hit the APPLY WEATHER button I get a message that says "Unhandled exception has occurred in your application..Value cannot be null. Parameter name: Argument 'Array' is Nothing."I have tried a fresh reinstall of FSX and I have tried updating to the latest Net framework. I am running Vista 64. Any help is appreciated.If I click details I get all of this:See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.************** Exception Text

I meant to say I tried a fresh install of ASX - not fsx.
