I've tested on more computers and spoken to other friends and we are all having the same problem.
I am using older openacs 5.1 and this is the link it tries to get them from;
http://localhost/acs-admin/install/install?package%5ftype=apm%5fapplication&repository%5furl=http%3a%2f%2fopenacs%2eorg%2frepository%2f5%2d1%2f
It returns no errors, and no results.
