Campaign map/button issue

[Gruggy]

Sorry if I'm posting this in the wrong place. Just registered on this site.
I have been making a campaign, but I encountered a problem where no matter what I try it doesn't seem to resolve.
After working on the campaign (the button and the first map etc.)
Once it said the file is corrupted/unavailable so I moved the map to a new file and now it just fades in fades out on the campaign screen and absolutely nothing happens. I checked that the file is loaded. I must've missed something totally obvious.
Please help

Edit: it's fixed. sorry for wasting your time

I can think of 2 things.

1. the map is bigger than 8mb (the map not the campaign)
2. the map path is invalid. If you re-import the map you need to re-attach it to the button even if the map name is exactly the same.
