Did you try to use the "Join Now" button on this
http://www.wyndhamrewards.com/uk/bmi/ to register? It seems like the requirement to be part of the promotion doesn't require registering for the promotion specifically. The equivalent of registering for this promotion involves having joined Wyndham's reward program and having selected BMI miles as the earning option. If you've done that, directly book your stays with Wyndham hotels and do your stays during the promotional period, then it seems like you should be good for the promotion for up to 4 stays without having to take any additional steps.
I used the above link to join up and selected a US mailing address -- that seemed to process fine.
