HELP tried making my first custom character (npc) Now the game endless

[Arigato]

I Followed the guide here http://www.youtube.com/user/ForAdventure on how to make a custom NPC. I followed everything to the T, and now I can't even get into the start screen. Even if i delete it the game STILL crashes, And even with high speed net, reinstalling skyrim would literally take a day (From steam)
