I recently loaded FSX in my other PC and everything was working fine. But this AM I started installing add-ons and now when I click on the FSX icon I get this big window from Microsoft Aces Resource Editor with nothing but blude screen and rows of blank columns on the bottom pertaining to Property, Instance, Type, Value, Description. I've added new airplane files before with no problem but this one puzzles me. What did I do wrong?

It's hard to tell.  It's always possible that one of the add-on's is the guilty party.  Try deleting them one at a time (and anything that came with them, like gauges, effects..), until FSX boots up, or delete them all and add them back in, one at a time, until FSX goes "Pthththththth!"
