Personal Macro not running

[Boytjie79]

I have some personal macros which are saved locally on my computer, the have been there a couple of years and have been working fine. However, a couple of days ago they stopped working throwing up an error, see screenshot. I have recreated the personal macros using .xlsm, xlsx and xlsb but they are still not working, any ideas? Many Thanks

Do a google search for "vba runtime error 400". There is a lot of information about this error.
