Oblivion GotY Edition - Game freezes every time I cast a Conjuration spell!

Oblivion: Game of the Year Edition

All Xbox Live updates downloaded

I reached level 55 in Conjuration and now every conjuration spell I cast freezes my game. I tried a different Conjuration spell with the same result. I downloaded all the updates, no change. I tried going up a few levels with a trainer but when I casted a Conjuration spell, CRASH! Then I tried it on my old character and it didn't freeze. I'm confused. Can anyone tell me what's going on and how to fix it? Is this going to happen with the other magic skills (Destruction, Illusion, etc.) when I get them to level 55?

EDIT: Problem solved. It's exceedingly strange. Once I leveled up again my Conjuration spells suddenly began working again. Thanks for your time. =)

i remember this happening to me. i found out that it was because i was wearing perma-bound armor but once i took them off, it was fine.

hope this helps.
