I recently had problems with my computer which meant the loss of my CD-DVD drive and I had to use a game crack to access my Oblivion but as soon as I loaded my Oblivion I noticed some meshes were missing namely almost all helmets and many buildings. Do any of you know how to get all the default meshes and textures back, or as a last resort. How to un-install and re-install Oblivion WITHOUT the CD-DVD disk.

Discussing using No DVD cracks is not allowed here. The only thing we can recommend is buying the game again.

You will get no help here if you use a no-cd/DVD crack.
