Sorry bro, unless you pay them, they can't help.
I've spoken to some people in industry who use Maya as a job. They have this problem all the time. Unless you pay for the program, the staff won't help - this is from over 3 months experience of my contacting the team and them asking for the same thing again and again without bothering to read what I have said.
I recommend wiping the computer completely, which might work, or resulting to less legal versions. Although the software offer is free, the maintenance on it is poor and the program rarely works. Other students in my class have had no problem for a while and then Maya decides to give the licensing error on them.
Sorry that you're having the same problem, I really am, there sadly isn't anything to do though.
