I've checked my email address is my AdobeID. It is.
Was it possible to register for Kuler before without AdobeID, because now I'm wondering if I used the same username for both and Kuler thinks I'm logging in with a Kuler username rather than my AdobeID. Don't know.
Thanks in advance.
Is possible you might have had more than one Adobe ID, maybe a second one under a different email address?
