We had an old drupal install which had custom content, but I'm not sure which type it was (either a custom content type or whether it was in a blog, page etc). It has 4 db tables and from the home page was a link '?q=project'

I upgraded the install from 5.2 to 6.14 and all has run fine except with the project content. The above link is broken and because I am not sure how the old one was set up, I am a bit stumped as to how to link to it. I tried setting up new content type and it allowed me to view the content in the admin side, but I was wondering how to get the '?q=project' link working again.

The data is obviously still there but only in the db and not in the user end.

Any help appreciated
