It's the site. Been goin' on for days!
My tip:
When you first hit "post message" and the site says "no dice", just ignore it. Your post is going up, and it'll go up again every time you hit that button!
To O.P.
Your fabric might have shifted a bit along the rail and gotten "off square". Happens all the time, especially if the little fabric retaining screws on the roller/rail have fallen out. You'll need to slide it back to square.
You should be able to determine which way it needs to be shifted by looking at which side is "off" when you try to roll it up. Once you've figured that out, open the awning and use the arms to hold in place with a little sag in the middle. (Takes the tension off the fabric). Grab hold of the end on the direction you want the fabric to move and give it a tug. Should slide pretty easily. Once you have it where you want it, which might take a couple of tries, do put some screws in it to hold it in that position.
