Hey Cheri...
I have the same trainer (and was riding it at 5:30 this morning!) and had to fiddle around a little with the L-bolt to get it in place. Like you I had some trouble with that same step, but moving it around a bit got everything in place.
I hope you have a powerfan inside, because it does get warm. Oh and I've found training indoors raises my PE by a good 1-2 points at the same power level vs. riding outdoors. I suspect you may find that to be true in your case as well, so be ready!
