Hi,

I created an Automation Add-in for Excel 2003 using c#

I installed this add-in and everything functioned well till yesterday.

Today, all my worksheets crashes when they call functions from my add-in.

the strangest think is that I can use this functions in
Access/Word/VbScript
but not in Excel.

Does someone encounter this problem?

Thank you for your help
