simple autohotkey (AHK) code

Hello coders, I have an exisiting autohotkey script that is always running. Its an autohotkey (AHK) made into an exe file. - I need someone to write some code so that the script auto reloads/refresh's at a certain time each day. I need a prompt/GUI to tell the user this is happening prior to and after the run. Coders will not need the running ahk file. Just write the code to reload/refresh it AT a certai time of the day. Thanks.
