Skyrim Mod does not work anymore?

Play Skyrim on the Xbox one and I downloaded the Mod Amazing Race tweaks for the race Nord. Yesterday still worked perfectly, today in the game, but again started again (not changed s.den mods, etc.) and suddenly I miss all the skills and the mod does not work properly. Did someone ever have such problems (maybe even with this mod) and can somehow help? Would be very grateful.

No, you can't… Bad luck. That's just the problem, if one thinks to have to pack up every stupid mod.
