Your account has likely been suspended for potentially violating the Contributor Terms of Use. At this point you should contact Adobe Contributor Support using the link they provided when you attempted to log in. Adobe will reply most likely within a few days although it may take longer. Make sure to watch spam and other folders, my Adobe emails get filtered to the Promotions tab of my email service.
There may be an investigation that could last several weeks. One user reported the investigation lasted 4 weeks.
Be patient while Adobe works through the process, and be polite with any follow-up correspondence.
The members of the forum aren't employees and we aren't able to help you other than advising you to contact Adobe with the link that's been provided when you log in. Adobe will only communicate with you about this via email. Good luck!
