Tried in WP (vincentdegroot.com) to enter my account details for Responsive Pro. It reports that my account is invalid. I have reset my password here to be absolutely sure I have it right, this did not help.
– When I try to edit my profile I get a not found message.
– The site here already has the right aviatar, maybe this is taken from my other site (photo-vinc.com) where use the free responsive version.
