'special' path not set for debug build

I am trying to build and run XBMC Frodo branch under Windows and have it compiling with VS2010 but it fails to create the application because seems the 'special:' path is not valid:
Loading player core factory settings from special://xbmc/system/playercorefactory.xml.
special://xbmc/system/playercorefactory.xml does not exist. Skipping.
Loading player core factory settings from special://masterprofile/playercorefactory.xml.
special://masterprofile/playercorefactory.xml does not exist. Skipping.
No settings file to load (special://xbmc/system/advancedsettings.xml)

Default DVD Player: dvdplayer

Default Audio Player: paplayer
Disabled debug logging due to GUI setting. Level 0.
Log level changed to 0
Loading media sources from special://masterprofile/sources.xml
creating subdirectories

screenshots folder:
thumbnails folder: special://masterprofile/Thumbnails
load language info file: special://xbmc/language/English/langinfo.xml
unable to load special://xbmc/language/English/langinfo.xml: Failed to open file at line 0

It is probably something trivial but I don't know what.
Thanks.
