Oh...Well that means you are not connecting to the network at all...
It sounds like the apartment building your living in is blocking p2p...
Or the ISP they use is...
You could try this, I'm not sure it will help though...
Try changing your port numbers...
Go To Tools > Options > Advcanced > Firewall..
and select the manual port forward box and change it to 64049
then change the listen port box to 64049 and select apply...
If that didn't help you can try..
Uninstalling your Java from the add/remove programs and then re-install the JRE 5.12 offline version....(4th one down)
Java SE Downloads - Previous Release - JDK 5
And last but not least..
Try deleting your preference folder...
Fixes for Limewire when LW isn't operating as it should
After deleting the preference folder and you still cannot connect, make sure you do the ports again...
If none of the above work it's definatley the appartments set up...
