I recently build a PC and installed steam with my usual steam login. Weeks later I get into CS: GO and wanted to sell a case but it says the market is unavailable. What it says right now:
The Market is unavailable for the following reason(s):
-You are logging into The Market from a device that has not been protected by Steam Guard for 7 days.
If nothing further occurs to restrict your access, you'll be able to use The Community Market on 1/26/2015 10:48:53 PM.I checked my profile and it says Security Status: Protected by Steam Guard
Now that its the 27th I still can't use the market, is there something else I need to do?

Steam Guard is a feature set in stone to prevent people from gaining access to your steam account and trading everything to themselves, this was a huge problem in TF2 some time ago.
For example, if you log in to your account at a friends house and forget to close steam, he essentially can't steal your stuff.
The way this timer works is the exact time you re-activated steam onto a new machine, and you must wait exactly 168 hours until you can trade or use the market again.
