Well i have been having some problems with the maps in both Oblivion and Shivering Isles...
Now the problem is i cant see the entire map in Cyrodiil like i cant see some of the map below Leyawiin and in Shivering Isles i cant see Mad god boot allmost that whole part.
Note i dont not have any moded map i have the normal oblivion map and the problem is still there.
So dose any one know why map is like this?
And if so is there anyway to fix it?

To return to the default, just delete the map textures you've placed in the Data folder.

Umm.... well i deleted the map textures but i still have the map problem
And just so u know i cant even go below Laywiin at all with the map so i cant see any thing or locations i have.
Edit:Well i reinstalled the game and still have the same problem.....(and it is not a mod or mods that are making this problem happen)
Not sure what to do now....Can anyone help me?

Well i found out what the problem was....
It was a HUD mod it made the map bigger but some how messed it up.
