I managed to work around it but had to buy the 522 at full retail and activation was a nightmare. The regular csr number will give you different results on the same issue almost every time you call. Either they change their policiy so much that the csr doesn't really know what's going on or they don't train them properly, however I will say that they try and I didn't blame them personally.
From what I understand they are no longer activating this box for existing customers and it will be near impossible to get it passed the exec office, so I don't recommend buying it knowing this. If you know an installer that can call the installers number at dish they may be able to get around it but even then I wouldn't trust it at this point.
