I paid full price to subscribe to music file sharing and it was deleted from my computer after 3 months of use.

I purchased the 360 proshare to download music and have not been able to get into it since April 21/07. I have removed it from my programs and now cannot get it back. I had purchased a lifetime membership... What is going on with this... I have gone to the site to try and redownload it but it wants me to sign up again and pay. I don't think so...
