Got it to work thanks, preloading.Signed in as usual but this time it worked, then clicked activate and it said the game as been added to uplay.
Chrome and Firefox I kept getting login errors.
Try this if it still doesn't work
Microsoft Edge
- Click on More actions in the toolbar and select Settings.
- Search for View advanced settings and click to open.
- Look for the section Cookies and select Don't block cookies (default) .
- Restart Edge to finalise the process
Lets hope that the buyer of my second key manages but could they not just have bunged a key instead of all this?
