Maximum number of authorizations reached!

[carlovalla]

I’ve reached the maximum number of authorizations for a book therefore I've cancelled the authorization for my PC in order to give the authorization to a colleague. The colleague tried and couldn’t get the authorization because the system reply that the maximum number has been reached.  Then I Tried again to authorize my PC and I received the reply that the maximum number has been reached as well. What can I do?
