backup DB -try to rename it in my BO- ERROR: The database selection cannot be made.

[L. Brett Sinclair]

Hello
I'm using v1.0.
I wanted to test the backup procedure. So, I backed up the files. Created a new DB. Imported the files.
On my Back office, I wanted to point to my backup DB.
I changed just the server name and DB name and I clicked update (or save) and now I'm stuck ! :bug:
my front or back office display: "The database selection cannot be made."

Help would be much appreciated.
