well i see i am not the only person with this problem, mine just happened suddenly, no new windows install. was working the night before then no premium account detected, i received the same "help" suggestions that did not resolve my issue. my emails to support go unanswered, seems this company is not capable of supporting its own product beyond amateur trouble shooting methods.
i was very satisfied with the product, i purchased lifetime subscription just to have the feature of creating playlists. now i am trying to decide to purchase it again, however, i am concerned that this will happen again and i will be stiffed for another fee.
