I don't know about the whole anti piracy thing (not going there at all) but I do know that since 4.52 my copy of Vue Pro has been rock solid with the exception of when running quicktime at the same time. I do know that what seems to be going on with some users is that everybody has a slightly different configuration on their systems (non vue software utilities, virus protection, etc...) and a lot of the errors people are getting probably stem from not everybody running exactly the same programs and having the same specs on there machines which makes it harder for e-on to track down exactly what the problem is. Just my opinion.
