it may look like it 'worked', the thing is it doesn't work with the first click on the button.
one must click twice or hit return.....so I added an additional RETURN at the end and now it works with a single click. A minor quibble to be sure; but we are very gratefull and totally happy!
As now it is a simple one-click operation and much more likely to be used by the user to save them from the Recovery Manager failing to manage to recover the file.
The Civil 3D world will forever be in your debt!
