Firstly, have you checked to make sure that your site paths are correct in both bbPress and WordPress? Since you shifted directories, the paths to those new directories need to be adjusted in the database.

Secondly, are there normal user tables to go along with those weird empty ones? Part of the integration process is telling bbPress which tables to find your users in. Is it possible that you added an extra “_” on accident, and bbPress created those tables while it was looking for the real ones?
