I just received my educational version of X4 yesterday, now before anybody comes down on me for getting the edu. version, I am a vo-tech student for about 3 more weeks, and I figured I might as well go ahead and get the $89 version while I'm still a student. But, Amazon didn't ask for any student documentation or nothing, all they wanted was a credit card number. I know about the non up-grading features of the edu. version, but I think this will last me for awhile. Now my question, I'm running v12 right now, can I load the X4 and run it separate, or will there be some kind of conflicts having both on the machine? They won't be both running at the same time of course, and, my v12 has 4 disc, this new X4 only has 1, what's up with that? Thanks Mike
