Was it frozen solid, or just slush? There is a difference.
If you got all the water out, and had pure "pink stuff", you should have been fine....it will turn to slush, but not freeze to the point of damage. After all, slush can still move in the lines, so it won't expand out-ward, busting tubing.
The one think you didn't mention, or you didn't do, was to pump antifreeze into the water pipes after you blew them out. The reason I recommend this, is because you may still have water in those lines, where the air has blown past it (say in a dip in the hose)....if you pump the pink stuff through the lines, you know that there won't be any water to freeze. Well worth the extra $$ for another gallon or two.
Blowing out lines with air only works if done properly. Air doesn't freeze except for a little moisture that falls out of it. We only get to 20 to 30 below zero here in Wyoming. Maybe if I lived where it was cold it would be a problem but I doubt it.
