I don't understand.

I , dont understand ... ?
Care yo explain in better detail ?

That was it.
After someone said : Another trade where the owner has the games activated in his account.
the creator closed the trade.

I dont understand why the trade had to be closed.

I think the trade thread creator was trying to trade games which were activated on his account & in his library.
after realizing he can't trade the games unless they are in inventory as gifts he closed the trade thread.

maybe the guy who said that meant "Another trade thread where the op doesn't have the games activated in his account." and he/she meant the games op won from giveaways?

But how did some other person know that OP had already activated the games? I couldnt see them in their library?

This was the trade,

I'm still confused

Well, fuck, what a coincidence. I have the guy who posted that comment in my friend list. I'll ask him.

Sa6peto said "Um ... maybe , just maybe ... the trader guy was a newbie ... who tough he can trade games that are activated.
And upon realizing he cant ... he closed his treade ?" This. He was a newbie, meeting too many these days.

I also talked to him on steam, so I knew he had the games activated. That's why. No pm system
