Mozilla Thunderbird Question

On Friday my Thunderbird crapped out on me. I tried to click on a URL in an email and nothing happened. I clicked on the link a couple of more times and never got to the page it was pointing me to. At the same time my profile was removed as the default in the software. I am pretty sure that the profile still exists in C:\ Documents and Settings. My question is how do I point Thunderbird back to that location so that all my folders come back? I tried pointing to the directory that I think has my profile in TOOLS > ACCOUNT SETTINGS > SERVER SETTINGS, but that doesn’t seem to be doing the trick.

There is a forum with Thunderbird experts. Although it doesn’t get as much traffic as the SDMB, it gets quite a bit, and everyone there knows what the product is. See http://forums.mozillazine.org/viewforum.php?f=28&sid=90323884d616f3be9de59682a1bc9796 .

I’ve tried to search that site. It is next to impossible.
