XBMC loading problem

the harddisk of my little asus701 was really full, so i decided to move xbmc to an external harddisk, using the -p command line option.
then i cleaned windows with ccleaner,
Running windows xp, a stripped version.

Now the situation is the following:

1) if i execute "xbmc.exe -p", the loading won't go past the screen logo, and behind a windows error message pops " XBMC: Error - ERROR: Unable to Initialize. Exiting." If i click ok, xbmc dies.
2) if i reinstall Xbmc, deleting everything about xbmc, the first run is ok, but as long i quit xbmc, it won't quit and always needed to be force closed. Then it go back to the point 1)
3) if i move xbmc back to the old folder, the same as 1)
4) not using -p, is the same as 1)

well this is a curse? i wonder why uninstalling and reinstalling cant fix this.

thanks in advance
