odd

couple of troubleshooting suggestions:

if you can connect, check transfer speeds from a reliable source (download one of the files from www.magnetmix.com --I just checked and got the transfer at 124KB/s). Transfers usually depend on the host.

Messed up user prefs? Check by creating a new admin user in OS X's System Preferences->Accounts. You can transfer the LW installer to the public folder of your usual account, or just get a new installer for the new account by going to http://www.limewire.com/english/cont...pro_lookup.jsp

If LW runs fine in the new account, then you'll know the problem is in the user settings of your old account.
