Thanks for the idea, but it did not help. I found some 4 Excel11.xlb under
the same user, deleted all of them. Excel hardly accepted to open once but
not twice !!!
The strange thing is that it works perfectly under the second user (not
administrator but wide rights) !!!
It looks like Excel is not activated under my user's name (administrator).
It's a Student/teachers version of Office 2003 - OS is Win XP Home edition.
If you have another idea, I am grid to receiving it. However, please be
clear because I am not a specialist neither english is my mother language.
Anyway, thanks for the help.

Hi,
I have installed office 2003 8 months ago.
Suddenly 2 months ago, Excel refused to open. In fact, it opens, loads the
add-ins, and stay on a grey page (no work sheet open), no menu is active.
When I close it (red button up right) a worksheet opens for a second and
Excel colses down.
The Microsoft support recmmended me to create a new user in Windows with
administrator rights, which I did. It worked for a month or so, and again the
same breakdown with the new user name.
Microsoft refuses to help because I have used all my hotline rights... and i
refuse to pay 50 euros for something that seems to be Microsoft
responsibility. Before suing them, can anyone help me ? Thanks
