Major conjuration bug (Oblivion)

[jcarson0408]

I've searched online for help with this problem nothing even closely related to luck. The issue is currently whenever I make a new character after last night any time I try to summon something with conjuration it immediately vanishes like the time is over, it spawns a foot or so above the ground first then vanishes, not sure if that's important. I did download a mod, but after uninstalling it and reinstalling the game I am confident it's not the cause. What's even stranger is it doesn't affect characters made before I started having the problem. Any help with this would be greatly appreciated.
