I talked to asakawa on WH, gave him the same info I am giving you now.
Log out of both sites, log into ZAM, then log into WH and activate. If that does not work for you, then contact me via accounts@zam.com with your log in infoz. Yes, your log in infoz, if you prefer not to do that, you can change the pw first, or you can just allow me to change it on my end.
