Can't get HTTP step to send POST data?

Yep it's v6.0.6030.1651 over here.

But I think I found it: I copy pasted the step from your project and I noticed the first property is:

<Encoding type='3'>1</Encoding>

Whereas the Encoding type happened to be '0' in my project. No idea why (maybe because I originally created it with a faulty VBP version?) but changed it to 1 and it works just fine now Thanks!
