I just got the OB CS, it ran fine yesterday but today when i use it it is very slow, everytime I click on somthing I get "Not Responding" and I have to wat a minute or 2, its very annoying, how can I speed it up?

Does it load slow, or does it do everything slow? Loading slow is normal - there's a lot of data to load in the Oblivion.esm file. Rendering can be slow too, if there's a lot of other programs running at the same time. Just browsing through items/spells/containers/npcs/whatever shouldn't be that slow.

What all else is running? What operating system?

As long as you are not doing a LOT of multitasking this thing rocks.

For example I could not pause ans start my mp3 music with my keyboard media controls unless I restored the player to full screen first.

But just for ruining the CS with OBSE and the oblivion game it is absolutely worth the $15 cost.

Why would you want to ruin the CS?
