Hi,
the install file didn't quite do it.
What do you mean by "quite"?
1 problem: path to files (it doesn't work for admin and site in the same time)
Are you on a windows server? This is a common problem with an easy fix that has been discussed many times on this forum.
2 problem: ERROR checking id item availability dates Unknown column 't1.the_date' in 'field list'
It looks like your creating the tables manually didn't work either.
I suggest that you delete everything and start again.
Whilst this script has a couple of known bugs it has been successfully installed on 1000's of servers so it *must* be possible

Do you have an url that I can see (pm if you prefer).
Also I would be happy to take a closer look at the problem but I would need ftp access to be able to do so.
