[Plugin: Events Made Easy] Event links broken

Hi
I am having trouble with Events made easy. I have been modifying the way the events list is setup, organising it into categories and stuff and that all worked well. Although now all the links are broken and produce a page not found error when i click on the events.

Does anyone know how to fix this? I need to sort it out asap.

Thanks for your help 🙂
