It either no longer exists (data restored from an older backup), or it never existed in the first place (sql installation script wasn't run, or the table prefix wasn't set correctly).
As per my previous message, having additional fields (fields that are never referenced) in a database isn't going to cause any problems.
You won't. THAT IS WHY YOU ARE GETTING THE ERROR MESSAGE!!
My suggestion to finish the installation will probably be easier, but do it your way if wish.
Again, as per my previous response, you either haven't uninstalled all of the .php files that were installed by the module, OR you haven't reverted the modifications it performed on existing files. It can't be anything else.
Did it ever occur to you that the developers toolkit may not be searching all files, or that you only told it to search for functions or constants, or some other filter type.
It isn't possible, Therefore one (or more) of the .php files installed by the module hasn't been removed, or one (or more) of the .php files that it modified is yet to be restored to its pre-modified state.
I shall again repeat my suggestion, you will probably find it easier to complete the installation than it would be to uninstall it (assuming you have already placed the .php files into their correct locations). All you need to is run the sql script that updates the database,
If you feel you must uninstall then you need to find the .php file(s) that reference this field. If you don't find it/them then you simply aren't looking in the right place(s).
