Did you buy Pro from the official site Lime Wire » Official Website & Free Download « & did you buy it less than 6 months ago, for $18.88? Your Pro payment entitles you to free updates & email support for up to 6 months...if it's been more than 6 months then your email address won't be in the database anymore. If you bought Pro from another site, your email address won't be in the official database
