Don't think I've placed it in a trusted location. When I opened it in the first place it says it was read only and to save it with a different name. I did, to my documents folder and ran it from there

You can see the current trusted locations from Access with File | Options | Trust Center | Trust Center Settings | Trusted Locations. It is likely that your Documents folder and its sub-folders are set as trusted locations, which is why you were able to open the file once you'd moved it to there.
