I see that 48 times people have read my message, but no one wants to (or can) help me. Please, if you have a suggestion or if I need to include more system details, let me know. I have LW on my computer at work and it works fine. It's a PC and I simply downloaded the LW app. and poof! it worked. No messing with firewalls/ports/proxies, etc. What's the beef with Mac. Does this app. work on Mac without having to jump through a bunch of hoops? Am I installing it wrong? Any help would be appreciated.
