3D Studio MAX 8 : License Error, initialize the license management system

Hi,
I installed 3D Studio MAX 8 having such mistake: License Error, initialize the license management system. Must register in addition to install or re-install the product.
If the problem continues, contact your system administrator or authorized reseller. After these messages, there was also: software licensing system cannot select licensing system error. I wish to request experts to advise me to solve this problem. Emergency please.
Thanks
