There are no critical incompatibilities between xl2000 and xl2003 that would
automatically cause such a failure (that I have heard of).

I think you will have to experiment by removing aspects of the file in
xl2000 and then trying to open it in xl2003 and discover what is causing the
problem.

when I try to run a solution that was created in Excel 2000 in the Excel
2003, I had the Error "excel.exe application error", "unknow software
exception in 0xc0000409 0x30489b99"... Somebody know what is happening?
