Download link return to homepage

Hello,

I have been successfully using Download Manager for some time now and never had any issues.

However its been brought to my attention that the down load links are not working. the page is http://culchethhigh.org.uk/the-eagle-newsletter/ when a link is clicked it returns to the homepage.

If i log into my wordpress as admin the links work, but the settings show that the links are set for public access.

There are other pages on the site that use Download manager and as a school we need the access to the documents, this has come at a time when i was planning to purchase a full version for a new site.

Any help with the above would be much appreciated.

Thank you

Thanks, i cant install the update alongside the current installation, 2.6.8. If i deactivate it and install the new version it works but i lose the current files.

Any suggestions?

Thanks
