My achievements have an error because I have full orc and it says I don't have the achievement I would like to know if someone could fix that, also I want to ask is there a easy way of getting TC. (I'm not asking for people to give me some.)

Please wait 24 hours for the system to recognise that you have full orc.
If it still hasn't given you the achievement, please contact an administrator via PM or IRC and they will manually grant the achievement for you.

As stated above, you will have to wait 24 hours to get your achievement.

For your second question: There are several ways to get TC.

You can:

-Market (automated market, items board, and ingame (ingame marketing is not suggested though) )
-Bet (with /bet)
-Duel (with /duel)
-Play regular matches and earn 10 TC per win
-Buy a booster to get more than 10 TC per win
-Buy toricredits
-Do the 500/750 TC automated tournaments ingame
-Win the ingame tournaments hosted by Gamemasters
-Win the ingame tournaments hosted by regular users
-Participate in events on the forums, via the Events board
-Making and selling textures

These are most of the ways you can get yourself TC.

You've gotten the achievement, congratulations.
