Does anybody have any problems with this airplane and Vista?  I"ve downloaded to my vista laptop and has caused it to crash.  it will work, but i can't save it as default and have to start other aircraft first and then change the airplane after starting the flight.  after exiting the flight fs9 crashes.  i verified it's the erj because i did a fresh fs9 install with my pmdg 737 and it worked until i added the erj.  anybody have any ideas?
