Okay guys, I really need your help.

So I was playing Pokemon Black, when I decided to use my Action Replay. I found a code on Neoseeker that allowed you get all TMs. I used it, I was happy, and like an idiot, I saved before checking any glitches.

Upon returning to play the game without an Action Replay, I noticed two things: One, all of my HMs are gone except for waterfall and dive, and two, I can no longer get to the Dream World using game sync.

What should I do? My sister has a Pokemon White, should I just move all of my Pokemon to her game and restart mine?

Also, pic unrelated.
