Ok, I moved the file to the template folder and it worked so it was definitely a permission issue.
I’ve created a new folder called /js/ and put it in there and it seems to work. I can’t see a difference in permissions between them, but it works. Must be something I can’t see or a reserved word kind of problem.
Either way, thanks for your help!

Thanks.
The files are, respectively, in these locations:
C:\wamp\www\sbl\wp-includes\js\jquery\jquery.js
C:\wamp\www\sbl\wp-content\themes\sbl3\scripts\jcarousellite.js
Surely if the first one works then so should the second!?
Could WAMP, Windows or WordPress prevent access to the latter file like can happen on a server if your permissions are wrong?
