Hey, I have the same issue. Can we get some helps here ? I just bought TMUF. I want to convert my game to United version too, and it's saying Convertion cancelled : error http 12 157. I don't get it and I don't know how to get it right.. The key seems correct but doesn't want to convert.

Ok I found the bug. Go on your computer :
- Internet Properties
- Advanced
- Use TLS 1.0
- APPLY
and start again :)

Hello Casper and YuriVGR, thank you for getting in touch with us about converting your Nations Forever key/account into a United Forever key/account.

I can confirm, that to resolve this 12157 code, you need to press your Windows key on PC and type Internet Options and open this panel > Advanced > Scroll down to Security > Uncheck the 'Check for server certificate revocation option > Apply > OK

Next, in the same menu, enable the setting lower down the list TLS 1.0 and TLS 1.1 then relaunch the game.

After you have activated your key and converted it to a United Forever account, you can select Reset your internet settings to their default condition.

Make sure to undo these changes after your account upgrades, They were unchecked for a reason

Thanks for commenting this Bobinator.

We also advise resetting your TLS internet settings back to default after you have been able to access the game, as these earlier TLS settings are now out of date, so disabling them is best in the long run for optimal security, once you have access to the game.
