Thanks for the update!
Ha yeah, I did a lot of flopping around like an idiot, too, my first time out. (Actually, it was more like sliding and slamming down an icy blue run at night - which for some reason my friends thought would be fine for my first run and first time out! The memory of that icy run still haunts me...)
You and your friend are smart to have gotten a lesson
Hope the pain has subsided and that you get out there again and have even more fun.
Oh, and if you haven't already, definitely check out Snowolf's videos. I think they're in the Tips, Tricks subforum here and sticky'd. If you do a search you'll be able to find them. He may cover ways to get up.
