it is just my idea. an idea. so please if u have other 32 or 64 pc's it doesn't matter which OS try to install those drivers on them all and see how is the outcome.
this is not just for you but for anyone who read. if it goes well on all the 32 and bad on all the 64 then we have already found an important issue of the problem and the people from avid can concentrate to spot and correct and PUBLISH the corrected drivers. I hope they do
