Unable to untar studio 11 package

I am getting the following error while untarring:

bzcat: Compressed file ends unexpectedly;

perhaps it is corrupted? *Possible* reason follows.

bzcat: Error 0

Input file = studio11-sol-sparc[1].tar.bz2, output file = (stdout)

It is possible that the compressed file(s) have become corrupted.

You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover

data from undamaged sections of corrupted files.

tar: read error: unexpected EOF

Can someone help me?
