ddraw.dll missing from Directx

[sjl21]

Ive been having a problem with my comp(itunes screen transparent and internet flickering) and durring a system check i found that the ddraw.dll is missing from directx. I dont know if this is my problem but im trying to fix it and having no luck. I Tried to reinstall directx but i get a message saying that i already have the most current version. I also updated video drivers to no avail. I found a program to install ddraw but it wouldnt download. If anyone can held me with this id appreciate it. Thanks.
