firstly, thankyou for taking the time to help out a noob.
secondly, the problem;
i have made a basic character model and have been following a tutorial http://www.blendercookie.com/2010/01/04/rigging-an-alien/, which in itself seems quite good.
maybe its a bit ambitious on my part to follow this but i have ran into a problem and dont have the knowledge at the moment to resolve it.
i have followed the tutorial upto now, but when it came to the part about rigging the hand to the wrist, the entire armature stands static in pose mode. I thought at this point i shall backtrack to make sure everything else is still working okay, and now some of the bones have lost their influence. i have uploaded the .blend file if anyone wants to see that as im sure it will make alot more sense than i seem to put into words. im just unsure as to whether i have missed something or its a fault within blender 2.53 as it is still an alpha?
but yeah before i go off on a tangent again, thankyou in advance for any assistance.
