personally think it is necessary the pm will updated their system. the system should minimum creating the problem for new/exiting customers. as i have seen issues in the community, some of problem it is very simple. however it is kind of common to be happen in pm system. such as payment issues,activiation etc as pm online serve everything online it makes some difficulty for people so i believe a lots of people will appreciated if pm system will not create any extra problem for people who just want a simple life when they do everything right. i strongly recommand pm will see the problems has exist.
