Although my IPAD was synching to my IPAD, now it wont.
I tried on the IPAD, going to settings, synch, dropbox, synch now, closing and reopening the app, but the data on my pc still doesn't go the IPAD,
Can you confirm for me that the data folder you are using in 1Password for Windows is located in your Dropbox folder? You can check this in 1Password's preferences on your PC. Obviously you need Dropbox installed on your PC, but could you confirm for me that you have it installed as well?
