Sorry All,

Should be fixed now.  I was hoping to have it fixed before someone noticed
:-)  It seems Zone Alarm 5.0 and XP's IIS don't get along together.  The
problem has been corrected now.

hi Adam.

double-check that archive:
http://198.232.231.51/packages/AccessGrid-2.2-UNSTABLE-.fc2.tar.gz
i downloaded it and took a look at it:
.....
sucag1[root]43# tar tvzf AccessGrid-2.2-UNSTABLE-.fc2.tar.gz 
drwxr-xr-x root/root         0 2004-07-08 16:14:11 AccessGrid-2.2/
-rwxr-xr-x root/root       134 2004-07-08 16:14:11 AccessGrid-2.2/install
-rw------- root/root   1129130 2004-07-08 16:13:59
AccessGrid-2.2/xawtv-3.88-6.i386.rpm

gzip: stdin: unexpected end of file
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
....
i downloaded it again, thinking it was a transfer glitch, but got the same
file again.
