Thanks again..My problem is not exactly the same as those threads and the error comes at a different point...
LimeWire is installed, but the settings aren't finalized...
At the last step, the 'firewall preparation' window, when LW says it needs to "receive information from the network", hitting Next gets me an error box and the error message above. LW doesn't totally crash (at first)-- I can go Back and change options, but it won't go past that step. The alternate installer leads to the same results. However, this time I WAS able to re-install an old copy - LW4.26, which doesn't have that firewall step. So it seems that's where the problem is...but I don't know why. As I said I don't even have a firewall, just AV software, and turning it off doesn't seem to help.

I don't know if this is useful but here are my IP settings:
