1Password.agilekeychain not syncing with dropbox

I mainly use my iMac and also have macbook air and macbook pro laptops, all have latest versions of 1Password and Dropbox installed.



Dropbox is syncing all files apart from 1Password. Message just states -



Downloading 1 file...

Can't sync "1Password.html" permission denied



I have quite a few new passwords stored since last using my laptops and am going on vacation soon, please could you help me get my 1Password file syncing again



Many thanks
