I tried two Win7/64 computers, an XP laptop, my iphone and my ipad, and I tried enabling flash and using incognito mode... no joy.

Thanks, all, for the candid assessment of the site. I just got a Kickr and used my 520 to virtually ride a favorite route, but found that the trainer required much more effort than the actual ride. I'm new to smart trainers and power and was hoping a 520 user might lend some insight. I guess I'll look for a Wahoo forum.
