[MiKTeX] Problem with local roots

[Ignasi F. <ign...@ui...>]

Hi,

some days ago I reinstalled MiKTeX 2.9, now I did it as regular user.  
Today I've seen that MiKTeX Settings-Roots doesn't allow me to change the  
order of root directories. The order shown is:
nothing until "Show MiKTeX-maintained root directories" is selected, then
1.-D:\Documents and Settings\user\Datos de programa\MikteX\2.9 (UserConfig)
2.-D:\Documents and Settings\user\Configuración local\MikteX\2.9 (UserData)
3.-D:\MikTeX2.9 (UserInstall)
4.-D:\Documents and Settings\All users.windows\Datos de  
programa\MikteX\2.9 (CommonData, CommonConfig)
5.-D:\localtexmf
6.-D:\Archivos de programa\MikteX 2.9 (CommonINstall)

3 is the new folder for miktex and 6 was the previous one.
5 is my local folder with private packages and unstable versions. I did  
not explicity add it to the list and I would like to be in upper positions.

I would like to know how to 'repair' it. If I must uninstall and install  
again I would like to now how to do it. Which folders or file should I  
completely remove before a fresh install?

Thank you,

	Ignasi
