I can't spend points on the second gear of Affliction (Lordaeron)

Hello, I have a warlock on Lordaeron, level 17, so far. I haven't been able to spend points on the second gear of Affliction. Is this a reported bug? Is there a walk-around?
I reset the points and started over, and still couldn't touch the second gear. I don't have enough points to try the other 2 specs, and already spent my 1 gold resenting the talents to try this out.
If there is anything I could do, please, let me know.

SOLVED.
Just delete the "Cache" folder. This is a fresh download from Warmane, so I didn't even think of doing that, but it fixed the problem. So if you have the same issue, try that.
Let the eternal sun shine upon you.
Have fun, guys! =)
