Funny Winds at Airports.

I use FSMeteo to generate my weather and I have noticed just recently the winds at the airports are not the same that FSMeteo says they are. Since I use this information to make my flight plan in FSNavigator it is important that I get the runway info right. The past two flights I have been on final and asked for landing and they state that the runway in use is the opposite of the one I believe it should be using the information gathered from FSMeteo. As you can see it can cause quite a headache. The funny thing is that the display in FS2002 (Control "Z") displays the wind correctly, but when I tune in the AITS the wind is different (This is on the ground mind you). Should these winds read the same? Now I have recently been fooling around with TTools for AI traffic but when I put back my original BGL file the same problem presisted. SO I do not think that is the problem. I have FSUipc etc. and it hac been working fine until recently. Any help in this subject would be greatly appreciated. Thank you in advanceDaniel
