Don't worry too much about the connection issue for now - if your LW hasn't fully loaded then you won't see a connection.
Did you make sure to remove
all other Java versions & just have one version installed at a time? Did you try the older Java (1.5.0_11)?
Did you have any trouble with finding/deleting the preferences folder? Once you'd deleted the folder, did you have to go through LW's setup wizard all over again?
Did you try changing compatibility (right click on the LW icon on your desktop > properties > compatibility. Try running in compatibility mode for XP)?
When you uninstalled LW, did you do so from Add/Remove programs (or whatever Vista's equivalent is)? Or did you use LW's uninstaller (start > all programs > LW > uninstall)? Try removing LW again & follow LOTR's advice in this thread:

That post has a link to CCleaner, which a lot of people swear by. Also, there's a different link for downloading LW...just in case there's been some problem during download of LW.
Have you tried other p2p apps?
I don't use Vista, but I thought you had to have an admin account to install LW?? Are you able to become an administrator?
Sorry for so many questions
