Authorization Code for 3dsmax5

I´ve been using the 3dsmax with the authorization code for 1 year, when a error happend, error [6020].

Now I must obtain the authorization again, but this time the request code is:

  • 5452 0295 2205 4435 3958 9586 2421 7828

Any one know how to take an authorization code to this request code???

Sorry my bad english…
