Fix a microtech ultratech?

[HappyDonut]

I recently got a microtech ultratech from a trade, but it's not firing. I have no idea what's going on and I refuse to open the thing up.
Do you guys know if I can send it back to get fixed up or is there some kind of stipulation?
Is there anyone here that can fix it up for me if I send it to them?
This is my first microtech as well as otf auto, so I'm sort of hesitant...
Anyways, thanks for any answers.

Try posting in the auto forum, might get more responses. I imagine the spring is broken or something, but I'm not too knowledgeable on autos, though I collect them.

Can you move the blade in/out with your fingers? If so, pull it all the way out forcefully (be careful!) It should click into place. If it does, you have "fixed" the knife!

Check if had "derailed" (What Bill DeShivs described) If that's not the issue- open her up
