problems retrieving new forecasts

I’m having problems retrieving new forecasts/current conditions. I’m using WW 5.4a running on Win 2k Pro (with McAfee firewall - set to allow access to net for WW)

It works fine for about a day after I install it and set it to auto-update. Then it stops updating. If I try to update it manually, it shows it’s little progress/status window, shows “” for a couple of seconds and then disappears. The current conditions don’t update (including the last downloadsd and last updated times) and neither does the forecast or any of the other info…

If I uninstall and reinstall it, the above prargraph repeats…

Any ideas?
