Hi John,
Please see below
Can you edit macros in other workbook files?
No
Is it just this workbook or all you open?
All
When you click the plus sign in VBA editor, to you get a prompt asking for a password?
No
Could someone else locked your VBA project?
No
Do you have another saved version of this workbook you can use that allows you to edit your macros?
Yes I have another version and yes I can edit in that one. (The macros are all the same)
Thanks

Ben
