Problems with Meljet 772/3

Hi guys,
Got quite a horrible problem with my 772/3 from meljet. Everything's perfect when I'm flying them, the after a terrific flight, I come in to land beautifully, straight down the centreline, this is in crosswinds, and after touching down the bloody nose gear goes straight through tarmack!! Everytime I land in a crosswind that happens, it's bloody annoying, and what's pissing me off even more, is that now it's doing it with no weather on, no wind at all! It's not happening with any of my other planes, I don't have a clue what's wrong, I tried going into the aircraft editor, but couldn't find a thing wrong! I'm flying with most of the settings switched to off, just the scenery complexity and the terrain texture size is on medium, and all the boxes at the bottom right are on. Please could someone tell me what's wrong. Do you think it could be that my processor can't cope and that it doesn't help the flight dinamics too much, the meljet 772/3 is very detailed and realistic. 766MHz.
Thanks,
Greg
