Same issue here, for an address in the Republic of Ireland. Address is as specified by the national post office so 100% valid. Tried various variations (space, no space, etc.), same issue. So it seems their address validation system is broken for quite a few countries.

The irony of it is that they pulled these details from their own database (existing customer) but would not ingest it back when the additional field (re. job title etc.) had been filled.

Doing this to get a free license for Fision Player 13.

@VMware could you fix this please? Thank you.
