If you had a premium membership then you had a lot more room for PM's. If your subscription expired then it would have left your PM box full if in fact you had used more that the allotted regular member space. If this is the case you will need to go delete a bunch of PM's or resubscribe for a premium membership. I can mass delete your PM box if you would like. I can't read your PM's but I can mass delete any users box.
