What keywords are you targetting to determine that makes you think you are being penalized? If you are only basing it on PR as mentioned by others PR has not updated in a few months and PR does not guarantee high rankings either.
You currently have 77 pages listed in google.

You are also listed 11 in google under "EPIC-Credits".
