They offered to take it back and that was the option I was going to take. But instead they sent me the instructions to do it.
You should have just sent it away as you say your a novice so Eyetech should do what was needed,
if you did mess up something then Eyetech should charge for labour, parts etc instead of sending stuff to you when you told them you did not know what to do.
This is unacceptable Eyetech, sort it out.
