Hey people,
Can someone please tell me that if I uninstall Vray from my machine and then reinstall, do i have to get a new Authorization Code from Chaos all over again??..Natty,vlado,someone?..thx in advance. 
I dont think so. Vray auth codes are based on hardware, and your max serial numbers.
The only times you may need a new code if you change mobo, hardrives, etc. or change computers.
