Photos have orange/yellow hue in Photomatix Pro?

[SoWhat?]

I took some photos in the mountains and decided to try out some HDR with photomatix, but every time I combined them, in the tone mapping section they had a really orange hue which couldn't be changed using any parameters. Has anyone else experienced this problem?
Thanks!

If you look at some of the HDR Groups on Flickr (like this one) you'll see that the yellows - if they are present at all - are almost always highly saturated in the ones where the Tone Mapping is too extreme. So..... you'd better put one or two of your HDRs in your gallery here for us to look at.
