This is my first posting: I hope I'm doing it correctly and will be very thankful for any help or suggestions.

BTW, I have not had any trouble running previous LW versions up to now

2. fw settings allow all connex to com.limegroup.gnutella
3. 150 GB
4. 36.6 GB
5. broadband 24 kbps
6. Tilgin AB Vood 452w_A

17. today's LW update

upgraded LW today to 5.1.2
when clicked to open it requests Java upgrade from 1.5 to 1.6+
the latest Java (upgrade 2) is installed
it still won't open (pls see attachment for a clear image)
I try to download the previous LW version but it keeps dwldng 5.1.2

Could someone please help me out on this?

Thanks,

Unfortunately only the newer intel Mac computers can run LW 5 because it requires Java 1.6. See http://www.gnutellaforums.com/mac-os...0-5-later.html about how to downgrade back to LW 4. You will need to remove the LW receipt file before the system will allow you to reinstall LW 4.

Thank you for the error messages images, that made it all so clear.

Thank you LotR for your very clear and concise reply.
I thought that might be the case but didn't think of removing LW5.

LW5 removed, 4.18.8 reinstalled. Downloading in spite of a brick wall.
So, I follow your instructions:
"Go to LW's menu bar, Tools -> Options -> Advanced -> Performance"
but I get something different:
Tools -> Advanced -> Mohito DHT Arcs View
and I don't know what that is or where to go from there.
???

OH .. sorry that was for windows users. Preferences is under the LW icon top left of screen next to apple icon. You will find your preferences in a menu under there. I usually use the keyboard shortcut: command-comma __ ⌘ , __ Command = apple key

So .. preferences/options -> Advanced -> Performance.

Disabled Ultrapeer abilities and all options on that page.
Restarted LW.
Brick wall still there.
(Listening on Port 45777, using UPnP Router configuration.)
It works, but is there a reason why the wall is still there?

The Brick wall might be your router's UPnP failing. One thing to try is, setting LW not to connect on startup. Wait until all your shares & incomplete files have loaded, then go to file menu & choose Connect.

Have you made an exception in OSX's firewall for LW? OSX Firewall settings for Tiger/Leopard

But the brick wall is not necessarily a major issue. Do you ever see people uploading from you?
