4.16 pro to 4.18 basic?????
 

I d/l 4.18 and it gave me basic...i paid for a year of pro and now when i hit already bought it says all my screen names are invalid.

Who did you pay for Pro & how much did you pay?

The only official site for downloading any version of LW is Lime Wire » Download LimeWire
The official site offers Pro ($21.95, free updates & email support for 6 months) or Extended Pro ($34.95, free updates & email support for 12 months).

If you bought from a scam site then sorry - you won't be able to download a new Pro from the official site.

If you did buy from the official site (payment to LimeWireLLC) then send a PM to limenathan & he should be able to help you out.
