The way in your first post is not recommendable.

There are two ways:
A. (complete cleaning)
- Upgrade installation (with or without uninstall mods), important is only deleting all old vb4 files and upload only new vb5 files.
- go to phpmyadmin and export complete forum db structure (only structure, not data) and compare this structure with an export of clean vb install.
- delete all not-vb5-tables or table-columns

B. (clean only vbshout - I think you mean dbtech vbshout))
- Upgrade installation (with or without uninstall mods), important is only deleting all old vb4 files and upload only new vb5 files.
- look at installation files \upload\core\packages\dbtechvbshout\install (files with numbers) and delete all the tables/columsn created in that sql statements
- install vbshout
