I really want to upgrade to 4.18, but when I enter my email addy, it says it's not in their files. I've tried the only three emails I've had in the past 10 years, and it still says no. I've been using Pro since earlier this year, and would hate to downgrade just because of a stupid email addy. Is there any way to send my purchase information BACK to the email I registered with... something, ANYTHING that would remind me which address I used?

Did you buy Pro from the official site? Lime Wire » Download LimeWire
Did you pay LimeWireLLC for Pro (check your CC statement)?

If you paid a scam site for Pro then you won't ever be able to update from the official site.

Did you buy Pro for a year or 6 months? Your email address will only be recognised in the official database while your Pro's current - if you bought Pro for 6 months, your email address stays in the database for 6 months, if you bought Pro for a year then your email address stays in the database for a year.

After you bought Pro, you would have got an email from LW with a link to your Pro personal download page. Have a look through your emails & see if you can find it.

If you're sure that you bought from the official site & your Pro's still current, send an email to limenathan (click on link) & explain what's happened
