(I have no idea why there isn’t a link to that page from the main page, or even in the main bbPress theme, but that’s a different topic altogether. 
As far as I understand, to uninstall and re-install you’d only have to drop the tables from the database. Unless you changed the template files or something, I don’t think you’d need to delete any of the files.
Just login to your db using phpMyAdmin and delete all bbpress related database 
I think it should start with “bb_”
Have login my existing WordPress cPanel, the phpMyAdmin and MySQL doesnt have bbPress database installed. Hope that we are talking about the same location.
Just checked with my provider support via ICQ, latter advise same location as above.
Thanks for your patience.
It won’t say that if you have deleted the tables in the database. If you can drop the bbPress tables you will be OK to install the program again (only reason this is fresh is I had to do it about 4 times to get mine right)! ! !
Correct me if I’m wrong on this: the installed tables will not show bb_ if you changed the table prefix to wp_ in order to integrate with WP. If that’s the case, what tables should I delete? I was thinking that the correct table to drop is wp-forums?
bbPress’ table prefix should never be the same an WordPress’. That will cause many problems, as you may have experienced.
bbPress uses the following tables. Don’t delete the ones marked with a *, since WP uses those too (hence the problem).
forums
posts*
topics
topicmeta
users*
usermeta*
tags
tagged
These all look like bb_forums (or whatever bbPress’ table prefix is in your case) in your database.
I face same Problem.
I want to reinstall as some of the configurations are wrong; so i deleted bb-config.php and all bb_* (7) tables
now its showing “ERROR: Could not establish a database connection”
