I recently copied over my Excel files (created in Excel 2000) to another PC with Office XP SP-2 installed (i.e. Excel 2002, SP-2). Files without macros open OK. However, files in which I had macros assigned to buttons display the following message on opening: "Macros in this workbook are disabled because the security level is high, and the macros and have not been digitally signed or verified as safe. To run the macros, you can either you can either have them signed or change your security level. Click Help for more information." I read the Help file but its kind of Greek to me. Anyway, I reduced the Macro security setting (under Tools | Options) from High to Medium, closed and restarted Excel and opened a file. Now I don't get the previous alert message, but another one asking me to Enable or Disable macros...I click on Enable macros. Then I click on a button or two to see if macros are working; then I get this message: "PERSONAL.XLS could not be found. Check the spelling of the file name....(etc.)" I click on Tools | Macro > Macros... but there is not a single macro listed there! Where have all my macros disappeared? How can I even digitally sign them if they are not even listed? [BTW, I don't want to register with Verisign just for this; the macros are strictly for my own use.] Do I need to recreate them all over again in Excel 2002? Can I just import them somehow from the other PC (Windows 98 SE; Excel 2000 SP-3)?
