Rogue Sneak/Hide

[Matthalas Winterheart]

I am currently a level 7 halfling rogue, both sneak and hide are still @ 50 skill. I am using them pretty often and they are not going up at all. I did try training them in Rivervale but the trainer said he couldnt train me anymore.

What gives? According to the wiki, i'm passed the level now where these skills go into effect. Cant figure out why they wont go up in skill at all. Any help would be appreciated.
