When you used BitSpirit before this, did you use ZoneAlarm as well ?
If so, then were you getting any remote peer connections using it?
I haven't tried BitSpirit but usually in BitTorrent programs it will say either L(Local) or R(Remote) beside the IP on the connected Peers list.

If you only get L then firewall is blocking something, if you get both L and R then it isn't blocking.

BTW these 9 files that you're sharing. Would you consider them popular? (don't mention names)
If they are rare files that you think not many are trying to find, then it could take a while for them to get hits. You could try disabling ZoneAlarm for maybe half an hour to see if that makes a difference though, just no internet browsing while you have it off. You could also try and leave Limewire on for a long time (eg. 24 hours) to see if anything shows up in the hits column.

Software like eg. PeerGuardian2 can in some cases make the Brick wall show as well.

I had that darn Brick Wall myself for ages before properly configuring my router, and am absolutely sure that files showed up in searches, because people uploaded files from me where I was the only host, which were not rated at Bitzi and I wasn't downloading anything (browse host not an option then). I notice a big difference in the number of hits I get now that it's gone though. The screenshot was taken after like 15-20 minutes after starting up Limewire.

In Limewire Tools>Options>Advanced>Firewall Config
What are your settings?
If the Firewall is disabled in your router then you should be able to just use manual portforward (use the same number both for listening port and forwarded port) Then Allow that port (Both TCP and UDP , Incoming and Outgoing) as an advanced rule in your ZoneAlarm.
