Ok , seems like I must appologise for insinuating that you were the one of the "legion of the scammed" as they are affectionately known in these parts.
I am not in the know as to the inner workings of LW but if you last payed over six months ago, you will no longer be eligible for free updates of pro. and as I said I have not heard of any discounts being given or offered.
I believe your best approach is either to use the feedback form, which I gather does lead to a reply in a few days at:
http://www.limewire.com/english/cont...egory=feedback
or e-mail feedback @limewire.com
These two avenues are possibly one and the same, and the subject line is important in that you don't want your mail to be overlooked as a trivial mail from a basic user.
I hope this helps and good luck!
