Clsemers, there is a way to de-authorize ADE and re-authorize ADE using a new adobe ID.
- Launch ADE.
- Press Control+Shift+D (Windows) or Command+Shift+D (Mac)
- You will get an option to Deauthorize or Erase Authorization(depending on your ADE version), click it and you are done.
- Go To Help-> Authorize Computer.
- Enter your credentials and authorize ADE.
Hope that Helps!
