Add me too the list of user who are experiencing the very same problem. I am
using Windows XP Office 2003 and opening this same file very week and now
suddenly it is not opening with no credentials failure. I have tried copying
the file to another computer and still the same problem ;-(

Hello,
I have a very important .xls file (created in Excel 2003) that I had
protected using my MS Passport account with IRM.
I have opened it many times in the past in both Excel 2003 and 2007.
Now, when I try to open it, I am told that I do not have credentials that
allow me to open this workbook, but that I can request updated permission
from MYSELF.
Of course, to update permissions, I need to be able to open the file in the
first place.
No other users that might have had permission can open the file either.
PLEASE HELP!
Thanks
