Excel add ins
I received Excel files created in Excel 2003. This had an add in in respect of Currency rates. I did some work on them. Now I have Excel 2010, but there are always error messages appearing.
In the past I have sent the files back to the senders, and they correct them somehow. Can someone tell me how to fix the problem myself?
Thanks.

I think we need some more information
Do you know the the name of the add-in? And what error message(s) do you get?
Is it definitely an addin and not a macro in the file?
Do you have any problems with other Excel 2003 files?
