help installing new library request

I trying to install a new fixture library that was created for me for some LED pars, but I can seem to get the file installed on my WH3. I've tried importing the file under preferences, but it doesn’t show any file on the CD. Then I also tried creating a new show to merge them together. The first time I did it, it couldn’t locate the network, the rest of the tries I can get past this error message "expansion of /cdrom/fixturelib_v4.hog3lib.tar.gz failed: cannot open archive for extraction. I tried doing it with the files zipped and unzipped noting changes

I wanted to have this installed and working before a show tonight, can i get some help?
