help finding units!

[Cheespuff]

so when i fist got starcraft 2, i was playing around with the editor, and i found some really cool units. like the Tarren-Tron, and Nova. but after that and now i still cant find them. :banghead: and i even REinstalled starcraft to see if that would work, but it did not.
Have any ideas? did i activate some filter?

-Thanks in advance
