The most common reason for this is a spelling mistake in your password. Note that passwords are case-sensitive so using the wrong case for a character is considered a spelling mistake. For example “ub78rt” is not the same password as “Ub78rt” (note the difference in case of the first characters, 'u' and 'U'). Make sure that your Caps Lock key is not turned on when you enter your password.
Ensure that you are entering your “Current” and “New” passwords in the correct fields. The “New” password must not have been used before. We advise customers to keep a list of the passwords they use to avoid reusing them accidentally.
In some rare cases when Internet traffic is high, the connection to the license server may time out. When this happens, the software may display the Activation screen instead of the Re-activation screen. The solution is to wait (15 minutes or more) and try again later.
