OOO - SaveUpdate not working

[the Savage Hippie]

Hey guys and gals.

I am trying to get Oscuro's Oblivion Overhaul running on my PC, but whenever I start the game a lot of meshes is missing. I have installed the game manually and moved all the meshes to my \Data\ folder and used the .exe to manual install the mod (twice).
I figured, the reasons the meshes were missing, was because I just pressed continue and played from my last saved game - so I had to update my save, however, when I at the end at the installer or manually try to use the saveupdater.exe it just says:

Errors
See the logfile
C:\Users\Username\AppData\Local\Temp\nstF93E.tmp\OOOupsave.exe.log

Notice: every time I try to run it, it will come up with a new xxxXXXX.tmp

What do I do?

Did you... read the logs, by any chance?

Save games shouldn't contain a reference to a mesh itself, so I don't think that's what the problem is. You might have put them in the wrong spot, or something else entirely might be messing it up.

No, I must confess, I haven't bothered to read the logs yet, I thought Andere or someone else just as wise would come along and tell me what to do. Oh, Akatosh, I am lazy.
