"This Steam account already owns the product" is BS "not true"

[HMMC]

PROBLEM "This Steam account already owns the product(s) contained in this offer. To access them, visit your library in the Steam client."


I previously purchased the base game "Sniper Elite 4" from GamersGate and it Redeemed on Steam just fine.
Today I purchased (3) game add-ons for "Sniper Elite 4" from GamersGate.
-Sniper Elite 4 Season Pass
-Sniper Elite 4 Target Führer
-Sniper Elite 4 Camouflage Rifles Skin Pack
These (3) items will not Redeem on Steam. SAYS I HAVE IT ALREADY.

There are (2) ways to redeem from GamerGate
1) Signed in on GamersGate, went to "purchases," and they have a button to take you directly to Steam.
2) You can just sign in on the Steam Client app, go to the bottom left corner to "Add A Game."
Will not accept them.

Says to look at my library > Not there . . . Searched Steam, not there . . .
I have 39 games at Steam. I'm not a newbie . . .
Never have had a problems with GamersGate.

If I had purchased anything Sniper Elite 4, it would have been recent. GamersGate does not show I purchased these (3) add-ons TWICE.

soudns more like you already redeemed whatever it was you purchased

Also sniper elite 4 only has those dlc available separately. so you should hve gotten 3 different cd-kyes for each item

you should prolly look at the store page and see what dlc you already own

it sounds mroe like you bought the wrong thing on gamesgate

Purchase from a legitimate key site.

Have you contacted Steam support? They would be the ones with the knowledge to what to do.

If its not sold on steam, then its not steam's responsiblity. steam is telling teh OP what the key redeems as. thats an issue between the OP and the 3rd party seller

Check the kind of Sniper Elite license you activated on your account

The issue is the Season pass contains the other two items you bought. So what you've done is activated whatever the first key gave you and now it errors out the other two you're trying to redeem.
