Help none of my changes in the construction set show up in game

recently i have tried to add a custom weapon into oblivion i got the weapon in fine and it looks good in the construction set but when i place it in the game and then save the esp and put the x on it in the oblivion launcher it not there when i go to pick it up. at first i thought it was my mesh but i put a regular steel sword in sane thing happened i tried moving stuff it all looked right in the construction set but in-game nothing changed i made sure to save to an active file , also when it saves the esp i go to the data folder but i cannot find it but the oblivion launcher and the construction set both say the esp is there. i have also tried reinstalling oblivion and the construction set. Also im using windows vista premium.

any help is greatly appreciated.

This can happen if you're using the new CS (v1.2) with an older Oblivion (v1.1). Upgrade the Oblivion patch and it should work.
