FSX shuts down at start up

[BROGY]

Since a few days my FSX shuts down during start up (at the moment FSX has to open de main menu).
The day before it worked perfectly.
I've recently installed SweetFX en FSPS Fiber Booster (demo version).
I have reinstalled the AMD Catalyst control center and all it's programs.
Could somebody tell me what could be wrong with this strange problem ?

Hi BROGY and welcome.
I suspect SweetFX! There are some tweaking to do before it runs. Read the readme file.
Try to remove the files from FSX folder and see what happens.

Thank you Major Bass.
Problem is solved.
