wrong code

It could be that someone is trying to access your account. I'm not sure there's much you can do about it, but it's actually a good thing, since it's preventing them from doing so. I would try changing my password, first of all.

If it's still an issue contact Adobe Support directly:

Beware of people contacting you via the forums' messaging system pretending to work for Adobe! Only those with an "Adobe Employee" tag under their name are legit. Also, Adobe will never offer to contact you via Skype, or use an email account that's not under the adobe.com domain...
