So I tried to update the dvd player on ideneb 10.5.5 and of course it crashed, and I know I am retarded for doing that. anyway I tried to reinstall it, and I get the error where it repeats the welcome screen so I boot it up and do the usual routine where I type /sbin/fsck/ -uw or something like that and it says

Kernal overflow space unavailable, so I cant get passed the welcome screen and I'm stuck. What do I do?

Please help I'm about the break my msiwind into pieces
