Had that happen one time, I bowed a couple of the rods enough to get out of the sewed pockets at the end of the rods. Got things straightened out and then put them back in. All the while I was doing this, as I later found out. There were several turkeys behind me watching. Boy that just added gas to the fire.
Now, I mark the first hub I want to pop open with a magic marker. Seems there is always one hub that opens easier and makes the whole process easier. I had one blind that didn't matter it was hard to set up. I sent it back and called them. Told them to send me another blind, but first make sure it set up easy. They sent me another one within a couple days. It was fine. Very good customer service - understand the company has sold, so can't say what it is like now. They also gave me a couple extra rods, extra netting and stuff bag for free.
