Hi;

I wonder of those flying the CS757 with block F in FS9 how stable the aircraft is?  Not FSX, but FS9.  I've had, along with others, out of memory errors in FS9 with other complex aircraft and I can see that CS's 757 is very complex.  

Are there out of memory errors that others are experiencing?  The cost of this 757 is quite steep so before I buy I'de like to make sure it is stable?

Does CS offer a money back guarantee?

Thanks.
