hit and miss connection

hi can someone please run me thru the steps of, and i'm not even sure this is right, but, "updating my host cache" or whatever that is. i used to be able to connect to bearshare all the time using 5.2.5. all of a sudden it won't connect at all and its been a few weeks now. i'm assuming it has something to do with this cache thing from what i've read from other posts. i'm just really super computer illiterate and wouldn't know where to begin doing anything like that. any help you can give me with this is greatly appreciated.

See step 2 here http://www.gnutellaforums.com/host-c...bearshare.html & there are connection cache attachments at bottom of the post. Step 2 includes a gif animation to show what to do. If still connection problems, try installing the Beta version.5.1 listed at top of that page.

Windows 7 SP1 is out as of tonight:
