hey sorry that did nothing but waste more of your time.
the only other out there advice i can give is disconnect your internet (unless you have a static ip address)
leave it disconnected for half an hour plug your modem back in. and i dont know if mac computers do cleanups of cache files privacy files and regesteries and speedups, but just give it the big cleanup/speedup/defragup/optimizeup. check your internet speed, then give FW another go.
