close but no cigar

[KTB <ktb@binary.net>]

I installed Communicator 4.5 but got a couple of errors.

tar: bookmark.htm: Could not create file: Is directory
tar: error exit delay from previous errors
     Installing communicator Java files...
     Installing additional component files...
     Registering communicator 4.5....
The Netscape communicator software installation is complete

I also can't get the browser to come up when I enter "netscape&"  I
looked in the 'nethelp' file in the usr/local/netscape directory but
didn't see anything about troubleshooting.  Help.
Thanks,
Kent
