A bit old topic but maybe you didn't solve your problem. Try to run Visual Basic Editor (ALT+F11) On the left side you can see two windows with PROJECT and WORKSHEET properties In the upper one (PROJECT) you can find Microsoft Excel Objects and Modules Open MODULES and there is list of all macros you made. If only one there is your Macro ... Rightclick at Module1 (name of macro) and Remove module Dialog will appear with question to save or export deleting module. If you don't need it simple remove the module. Save and try to open.
