it says I have 150 TC and ORC force costs 150 TC so when I buy it, it says have 0 TC.

I don't see whats wrong? Are you not getting the ORC force or what?

That means you spent your 150 TC.

150 - 150 = 0

I don't understand the problem.

Where does it say you have 150 TC?
Your profile does not show your TC, which means you have 0.

Anyway, I've sent you 150 TC so you can buy the item you want. - I couldn't transfer the TC because you don't have 20 qi.
