Unknown User Account

Hi Brink, thanks for stepping in *Wink

"Account Unknown" is from a user account that had previously accessed the item, and the account is no longer currently available. For example, the account was deleted, or accessed by a user from another computer/network."

As far as I know there hasn't been another Account on my machine, nor accessed from other computers or network.
Because I'm the only user. Could it not due to a major update of Windows? Some other folks allude to that on other forums...

Whatever the cause I'll try your method now and see how far I get...
I'll keep you posted *Wink
