Thanks, Abraham, but I'm still confused (senility setting in, I guess). When I installed V6, I didn't get an option to choose between 32 bit and 64 bit. Vue just saw that my OS was 64 bit, so that's the version that installed. I wouldn't expect a difference for something like this between xStream and Infinite, but maybe there is (I'm using Infinte). Did your xStream installation give you a choice?
