I had the same problem, I posted questions and the weatherbug forum that were never answered or acknowledged. I finally gave up and downloaded BB weather instead.....it doesn't have the temp right on the main screen like weatherbug, but it updates every 30 minutes, much better than the push weather that updates only every 12 hours.
Here's a thread talking about the weatherbug, it may help you out, some of the posts have troubleshooting tips, they didn't work for me but maybe you'll have better luck: http://blackberryforums.pinstack.com...ug_direct.html
Here's the link if you want to give BB weather a try, it can be found on Jerry D's mini version tracker:http://blackberryforums.pinstack.com/blog.php?b=322
