Account doesn't exist

You did not have a  Fotolia account?

If not, you need to contact Adobe customer care, as contributor accounts are tied to your Adobe ID, which is your e-mail address. However, if your e-mail address is a Gmail address, please note that a.b@gmail.com is the same as ab@gmail.com for Gmail, but not for Adobe.

You need to tell customer support, that you are looking for the Adobe account attached to that e-mail and if it is still active.

Adobe customer care can be contacted by beginning a secure chat session at https://helpx.adobe.com/contact.html?rghtup=autoOpen. Pop-up blockers need to be disabled, you need to accept cookies! If the chat window fails to open, or is non-responsive, use a different device and/or browser to start the interaction.

Important: Adobe does NOT contact you unsolicited by e-mail or direct message. If you get contacted by direct message from a person, claiming to be an Adobe employee, look at that profile and check if they bear the “Adobe Employee” marking under their name. Adobe support does not use Skype to give you support.
If in doubt, ask the forum.
