Hi,
I came across this problem when I deleted a BSV in the Config Tool, then created a new BSV with the same name as the deleted one and tried to import a BSV from another source into the newly created BSV - Aware just won't do it.
I thought that there had to be some information left over in the database which was referring to the old version of the BSV - and the remnants of the old BSV were affecting the way that Aware was dealing with the new BSV of the same name.
To test it, I created a new BSV with a different name and the import worked just fine. So Aware obviously hadn't fully deleted the old BSV.
I once more deleted the offending BSV in the Config Tool and then accessed my database (MySQL) and manually removed a number of remaining entries which referred to the deleted BSV.
Then I re-entered the Config Tool, created the BSV and successfully imported the new version.
Looks like Aware's BSV deletion leaves behind a bit of hang-over !
Hope this helps, but take care with accessing your database manually 🙂
