Yup, FS9.
Have FSX installed, but don't use it much, maybe 1 hour a month if lucky.
I honestly don't like the trouble it's worth. Too many little faults that stand out like a sore thumb, for me at least.
I know others love it, but I just can't get on with it, = the fact I have thousands of Euro's invested in FS9 to simply throw it away.
