The Elder Scrolls Skyrim (Trouble!)

[gamermini]

Lately when I sneak, I am ALWAYS caught and sometimes I am not even that close to the enemy yet. I don't get it! My sneak is at level 100 and I have all the perks already. It just started happening a few caves ago I guess. I let my companion go because I thought they were the ones making noise and same thing. It got to the point where I have had to lower my playing level down three times because it was more infuriating that frustrating. I have all light armor and shoes that muffle sound. Also, archers have lately killed me in a single hit too! I don't get it, what changed? I am getting owned by all the enemies and it is getting on my nerves. Why and has any of this happened to you too? Thanks!!
