HELP! GE: Changed Filter, Now NO Water!

I changed the GSWF water filter, as I have done several other times and now I have no water flow!

I returned my new filter hoping that was the issue and that did not resolve my problem.

HELP! Please!

Nobody has a suggestion? Anybody???

Evidently, a frozen waterline in the door is a very common problem. See this thread, look for my 2/10/2012 post (DIY-man), with pics.
