How could it be possible that the full functional demo doesn't works n I go forward to buy the product? And as "Zoser" was saying " I don't think it will work on both " for this I can say that during the installation process the software asks for Supporting Software "Maya 7 .... , Max 8 ...etc etc" where I have loaded for both the softwares as well. Even it comes in the PLUGIN MANAGER of MAYA 7 but after CHEAK-ing the load button, nothing changes in the tool bar or nothing special comes through which I can incorporate both the sofwares. I don't know what can I do now. Thankzz for ur helps .
