Issues with FSX and FS9

[TSR2]

Hi chaps,

I was having VC10 withdrawal so booked the next hop from LIRF in the VA.

At first I tried FSX, but getting out of virtual memory errors after about 10 minutes and it kills the sim.

I then reverted to FS9 and DM's VC10. This had worked before last summer. All was fine until I went to take off, and at full throttle, I couldn't get her above 60 kts. It was as though the brakes were on, (but they aren't).

I'm on W11. I think I've had the problem with FS9 before, but can't think what it is. Has anyone any ideas?
