I just went through the same thing about a week ago...I had a blind that was probably 6 or so years old and it opens and closes easy as could be, and I could set it up in about 10 seconds. The new one, no joke, probably took me 10 minutes to set up the first time. You are right, the hubs and fabric is very very tight.
What I did is just keep going around the blind and opening each wall up...Not engaging the hub and opening it completely, but opening it up to a square to get all the fabric to unstick from itself..then fold it back up and do another wall. Eventually you will be able to get one of the hubs to pop over with some pulling/pushing. If you can only get one of the walls to open up completely, leave that one open for a little while and let it stretch, and then close it and start with a different wall the next time..
Each time you get it set up, the easier it gets - and if you can set it up and let it sit it outside in the sun for a few days, it will really help break it in.
