Sorry for the unfortunate news Cathe, hope you get well soon.
So, in stating this maybe it would be beneficial for everyone to just postpone or cancel this pre-order. Why? So, you won't have the pressure (that is obviously on you) to hurry up with this project, since you have had set backs on the start/filming date since November.
Because, being realistic, this pre-order has lingered on since the announcement and we are now looking at the approachment of spring. This is just an option, because I can imagine the pressure on you for the deliverance of these 4 DVD's since it has not really gone your way since November.
Just a thought. I did pre-order and I do like your workouts but I just may have to cancel and just wait and see if things are more on schedule.
I am supportive of Cathe, but I have and many others need to look at this realistically. And this is not a backlash at Cathe, because in all fairness when will the injury be healed? It could be a week or months, and that is just the reality of it.
Wish you strength and health....
