Problems with unzipping files
Several users have reported problems with unzipping the files. The
most common error message is that pk-unzip or WinZip complain about
the wrong CRC checksum, and refuses to unzip the files (or if forced
to unzip, the programs won't work). CRC checksum or Cyclic Redundancy
Check checksum is there for purpose and to check that the file is
undamaged. In all cases so far, the original files have been correct,
but they were damaged during downloading.
- Download files with SHIFT-CLICK in
Netscape. Netscape may try to download the zipped file first on the
screen, and this may damage the binary file. SHIFT-clicking forces
Netscape to store the file directly in your system without displaying
it first. I have no idea how this can be done with other browsers, but
I'll add the instructions here if you inform me.
- Re-loading may not always help, since the files are cached, and
the cached version was damaged. The cache or the caches may be
anywhere between my and your computers. You may try to unable caching
if you can, but this is very system dependent. Many people have
reported that the problems disappeared when the file was downloaded
to a computer in another domain, e.g., to a home computer.
- Contact me and ask
me to send the file as an email attachment. However, you must yourself
authorise me to send you huge (>100KB) binary email attachments, and
check that you can receive them.
