Recently installed Xplane 10 and have noticed that the winds aloft have disappeared, above 5000 ft the winds go to 0.  Is anyone else having this problem?

I think in pre 10.50 betas (v10.45) winds aloft only work in the US (AFAIK), so this might be the issue?

work fine in b6 and 7 here in aus, was at  21000 in prr little saab chnaged dir TAS droped 40kts.
