Launching the game shows "Login Failed, please try again. ID: 5/1105" instead of reaching the main menu, blocking login entirely.
Also appears as: delta force error 5/1105, delta force login failed 5/1105, delta force login failed id 5/1105, ID: 5/1105, error code 5/1105, delta force 5 1105
5/1105 is an account-linking conflict, not a server outage — the game's Li-Pass account system thinks the email tied to your account is already linked to a different Steam account, and there's no in-game way to unlink it. The one player-reported fix that consistently works is creating a brand-new Li-Pass account with a different email address, which starts progress over but restores access immediately. A handful of players also report the error clearing after switching to the correct Steam account their Li-Pass was originally linked to, so check that first if you've used more than one Steam account with this game.
What to try
- 01Check whether you're launching from the Steam account your Li-Pass account was originally linked to — if you own or have used more than one Steam account with this game, switch to the original one first.Reported
- 02If that doesn't clear it, create a new Li-Pass account with a different email address. A player who did this reported it worked on the first try; it does mean starting Operations/Warfare progress over, since there's no supported way to unlink the conflicting account.Reported
- 03If you'd rather not lose progress, contact Delta Force support at service@playdeltaforce.com or through the in-game Player Support FAQ and describe the exact ID:5/1105 message — account-unlink requests have to go through support rather than any client-side fix.Unconfirmed
