    kFBL_InvPageVarChar          = 348,
    kFBL_CorruptedVarChar        = 351,


Both are VarChar corruption.

1.9.8 is old even for 1.x line.
You can upgrade to 1.11 version.

You can check ReleaseNotes.pdf from 1.11 archive to see if was fixed at
least one VarChar bug between 1.9.8 and 1.11.

If yes, then this can be source of problem.

You mean Vstudio b9.  But problem cannot just go away.
At least you need do XML dump and later load into fresh db.

XML dump. You can have in your app menu
    Rebuild Database

Which will do this operation.

This is bad. Aha. 
Try to use VAPP 1.11 to load database.

Deal is that Vstudio 2b9 will load XML into db 2.0 format.
I think this is NOT what you need.
