Levitate not working

Hello, it's been a long time (probably 10 years) since I last tried Morrobilvion and it's abosolutely fantastic.

I seem to have a problem with levitation though. When I try the levitation spell, I get a message saying that it needs OBSE v20 or higher. I've got OBSE v21 and I'm running the latest version of Morrobilivion (v065). I could probably live without levitation if I didn't need it to reach Divayth Fyr in his tower.

Any help would be greatly appreciated and if you need me to provide any more information let me know.

Thanks,

Toad
