I'm getting this message when I open my model with a vba program in an excel workbook. Is there a way to open the project? If so, how? If I can't what limitations exist?

Also when I try to open the mdl from the vba debugger pd crashes. Is this normal? (This seems to have been a temporary issue)

Thanks
