When I try to activate my stuff it says...

remove 668845 from set
remove 668842 from set
remove 668840 from set
remove 669358 from set
remove 668841 from set
remove 668843 from set
remove 669359 from set
remove 669360 from set

How do I fix this?

Umm, you don't click check on them, you hit activate on the side.

so you don't hit the check all?

How do i get to my Set thing?

Check the items you want in your set. Then go to the bottom and hit the button to where it gives you a seletcion of options. Hit the one that says the set you want then hit sumbit. After that you can edit the name of the set by hitting the word under activate called edit. To look in the set just simply click on it.

All it says is Remove from set or Add to set.

Hit add to set, and your items should be sent to your set.

I DON'T have a set!

Hold on I'm going to look at your deactivated items.
Edit: So you want to activate the chronos items?

Just hit activate by it.

Um okay..

If you got your awnser then I'll leave it to a mod or admin to close it..

Btw how did you remove your items from a set if you said you don't got a set.
