i just downloaded limewire 5 all ok but can't sine in on main screen where library is etc i use user name and password and does not work above it says g mail , jobber etc it keeps saying user name or password is wrong is wrong i've checked pass and user name its corect

I've never actually used the Share With Friends thing but when I log in with my gmail username & password, I don't have any error with username or password being incorrect.

If you're sure that you're getting username (what you use to sign into gmail, not your gmail address) & password correct, then post over at this other forum. You'll need to register there.
