[UPDATE] New Steam Guard feature to help protect your items
We are going to make some alterations to the current restriction to make it less sensitive for users. Once the changes are made we will be sure to let you know ahead of time before they go live.
For now, the restriction has been turned off. You are now free to trade and/or use the market if you were hitting this.
