Keeps saying i need to update

so ive been copying and pasting in the import tab for GS with new code for macros for my Lock but every time I click the import button after I paste the macro code it keeps saying I need the 2403 version of GSE. Does anyone know whats going on or what im suppose to do?

What GSE version of the addon do you have?

Its kinda obvious - You need to … update your version of GSE.
