Using mac OSX 10.4.2. Limewire basic works perfectly. Upgraded to pro and getting very erratic connection.Using same settings for both. Have searched forum but have not found answer - is there one? Cannot find a way to contact limewire although I have paid for 6 months support Can anyone help PLEASE?

LW Pro Support can be obtained by going here http://www.limewire.com/english/content/support.shtml & clicking on the Pro support link.

Can you give us a total desciption of your set up:
1. Do this test: Bug Report instructions & sample image Is the result True/False?
2. What firewalls you have?
3. How much ram?
4. Hard Disk space available?
5. Connection type? (eg: dialup, broadband, cable, etc.)
6. Modem & router brand name & model numbers?
7. Where are you trying to connect from (home, school, work, etc.)?
8. What version of Limewire (LW) & Java do you have? (Go to LW's menu Help>About LW...) Will show both LW & Java version.
9. Who is your isp provider (Internet Service Provider)?
10. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up.

Try deleting your LW preferences folder whilst LW is CLOSED. You will find them here: /Users/your_username/Library/Preferences/LimeWire
But make a note of any important settings you have b/c once you reopen LW, you'll need to reset your options.

I wouldn't believe it, somebody having the EXACT same problem as me.
