I'm trying to determine if my Slingbox Tuner has been fried by lightning.  It was working with my XP laptop.  Then I changed laptops and began using a Vista SP1 laptop.  I installed the Sling software on it, but did not attempt to connect.  Then lightning struck and fried my modem and my router.  I have a new router, configured exactly like the old router and a new modem.  Now I try to connect to the Slingbox.  Nothing.  I get the following error:

 The connection attempt failed. Make sure the  Slingbox you are trying to watch is on, set up for remote viewing, and not blocked by firewall/NAT settings.
Error: 0x8007274c

The router is a WRV54G Linksys, said by them to be vaguely equivalent to what I had.  The Sling is hard wired to the router.  My laptop is attached to the router wirelessly.  The router is unsecured.  The router does not have the default addr but is configured exactly like the old router.

I cannot connect to either my Slingbox or to a remote Slingbox.  Everything else on the network is back up and working fine. 
I checked Norton (which is new to me) and the Slingbox program is allowed to communicate with 64-16-232-2  outbound  TCP, 5001. 
I also tried to connect to both these Slings with the firewall on and off.  Same result - no connection and the above error message.

Both the power and network lights are on solid and apparently working correctly. 

So, have I forgotten something, or is the thing fried like the router and the modem?  What else can I do to answer this question?  I tried calling Tech Support, but they'd gone home for the day.
