Question How to get TCX Suite 6.1?

I am having trouble purchasing the software.

It seems shops only sell TCX Suite version 4.0. I see version 6.1 is out (downloaded the 60 day demo), but cannot find it in any store that sells it. My Dell rep does not respond to my inquiries on version 6.1, so I hope you can help me.

Thanks in advance.
