How to Install an Update
Backup your existing installation! This is important!
Then grab the new ZIP file from the download area and unzip it. Unzip live.zip and upload the contents of the Live directory to your webhost
Now run upgrade.php rather than setup.php.
It will create a new database table with your prompts in. Once you have confirmed it's OK then you can delete the old prompts file (promptdata.php).
If you wish to retain customisation then you should recopy your customised files from the backup you made before you started
The new files that HAVE to be replaced are as follows :
admin.php
adminprompts.php
prompts.php
adminpromptmodify.php
go.php
user/user-lib.php
adminupgrade.php
adminupload.php
That's it all done!
