Didn't you read anything when purchasing Pro? No refunds.
Anyway, try turning off the Mcafee firewall too and read
this about the AOL part.
Relaunch LW after that and go to Tools, Options and Bug Reports. Click the button for an example and go to the part where it says "Recieved incoming this session".If it says true, then the building's firewall is not in your way. False means the contrary.
If it's false, come back and we'll try some altenate ports.
