I purchased Limewire a while ago. When I tried to upgrade, it did not recognize my e-mail address. I used to be with ATTBI.com and now I am with Comcast.net. I even tried my old e-mail address and it did not work either. In the course of all this I received some kind of internal error and lost Limewire completely. I have re-installed the Basic, but how can I get my PRO back?
