Hi this is Suresh. I got an issue when my system crashed and i wanted to reinstall OS and all my software’s. I have reinstalled WinXP and i have 3D Max 2009 multiuser license(one key for 3 System), which i was not able to get register. Its dsplaying an Error message that “Maximum no. of user for this license serial is already registered” while trying to activate. But only two out of three license is activated and one system OS crashed. How to sort this problem? i need to activate my license.
