Hey people this is a connection issue not a beta issue (ie: should've posted in connection problems section.)
Captain Screwbarb make sure your LW options haven't changed (such as for your firewall - also check your firewall settings.) See this thread:

Confisk8d131 you said you uninstalled & reinstalled : was that LW or SP2? SP2 changes a lot of the settings you may have had before. Win's firewall is by default turned on when updating to sp2. Have a look at the above link. Also, unless you absolutely need it, why not uninstall sp2. It has caused havoc among businesses & personal users. Else, check all your settings & search this forum for sp2.
(once you install a service pack it's very difficult to 'fully' uninstall it. This was a M$ warning! - I should emphasise that note!)
