I have been asked by my outside developers to setup a local Redmine install and import their issues into my setup. I have the issue importer plugin showing up in the install. I have checked the box in the project modules. When I navigate to the project now, I get "page cannot be found". I think the db:migrate did not run or something.

The only thing I know about ruby and rails is what I have been trying to find in the past 4 hours I have spent trying to get this working.

Can someone please help me get this working so I can import the issue list from my developers? Worst case, can I get redmine back to normal and I will type them in manually.

Thanks!
