Unable to create a new User after you deactivate another

Unable to create a new user even after an existing user is just deactivated. User de-activation does not release a license to be reused if the org had more active users than it has license for.

Normally,  when a user record is deactivated, the license that was in use can be reused for another user of the same type. 

In some cases, however, user deactivation does not release a license to reuse. This occurs if the org had more active users than it has licenses for.

For example, say an org had at one point 10 licenses and there were 10 active users with those licenses. Then later, during a contract renewal, the org reduced the number of licenses to 5.

If the 10 users are still active, the org will have net -5 licenses.  When one user is deactivated in this condition, there will still be net -4 licenses. New users cannot be created until the number of available licenses is greater than zero.
