help!!!! i dunno how long i've been at it and how many people have tried to help me. But in stalled Mandrake 9.0 and after installing i went into rpmdrake to install the development packages, multimedia and all that and everytime it says!!! "Installtion Failed, Some files missing. You might want to update your sources database." Now i've downloaded and burned other copys thinking it was corrupt software. I've been given websites, and commands to use but nothing works. Can anyone help and or explain what the heke is the problem with this?!?! thanks ...
