I'm confused
Did you buy LW Pro, or 360Share Pro?? There's not much we can do about 360Share Pro as it's a scam version of LW...you'd have to go to their help site/forum, if there is one.
If you bought LW Pro, was it from the official site
LimeWire ? Pro costs $18.88 USD & entitles you to email support & free updates for up to 6 months. There is no password for the official Pro. After 6 months, if you don't renew your subscription, your email address will be removed from the database. If you bought 360Share Pro & are trying to download LW Pro from the official LW site then of course your email address won't be recognised!
