[newbie] rpmdrake

[kernell32]

Ok im about to loose my nerves rpmdrake wont accept any media that i tell it 
it worked before but after (dont ask me why ) taking out the default media 
(cdrom ) it tells me that it could not find any package and i should check if 
my network drives are mounted in case i did a network install ...
i tryed to choose from ftp and cdrom in both cases the same thing: "no 
packages detected"
any help wanted!!!
