Is it you cannot connect?
Is your LW or router port forwarded? Before you forwarded a port in the router did you set up a static ip first? If not done first, the process won't work & you would need to delete the previous pf rule & repeat process.
Static ip instructions for OSX 10.4
I am aware some apartment complexes have their own internet controls & firewalls.
After verifying your port forwarding above is correct:
1. After updating to the new version of LW, it's best to delete the previous LW preferences folder;
Deleting LW Preferences folder in OSX (make sure LW is CLOSED at that time, also make a note of all important settings.)
2. If LW still won't connect, try options here

3. Another option is installing
FrostWire & if it connects, then close it. Then try re-opening LW.
The performance options can be temporarily disabled as described in the link in point 2 above:
