Error in Authorizing Mac OS X 10.6.8

I used Mac OS X 10.6.8 and I am having issues on authorizing it. I always get “0xfd from Server – Internal Server Error”. I already re-installed License Manager but the error is still shown. The rest is working such as GearBox and POD Farm. I also have TonePort DI-G. I need help and advices. Thank you.
