GW2 DB - A local account matching the unified login...Follow

... could not be found.

I'm trying to login with my wowhead account (e-mail/pass) to guildhead and I get this error
"A local account matching the unified login could not be found."

When I first logged in to this site (zam.com) I got a nickname selection, where it was said I can use my guildhead nickname (ReplicaOfKzD). So, this basically means, I just can't access my account with guildhead, though it actually exists. I can't login with the nickname either, only e-mail is accepted.

I didn't find any usefull information with the search or google. Only found a few old threads on mmo-champoins with the same issue on torhead, but no solutions were suggesteed.

Hope for any help, I just don't like creating millions of accounts if it's possible to have just one.

Replica - try resetting your pw on ZAM/Wowhead and then trying again. If that doesn't work, email feedback@guildhead.com and we'll work with you to resolve it.

That's great to know ReplicaOfKzD! Thanks!
