Maintenance task error

I just started having an issue with my maintenance tasks. When I click on one of my tasks to modify it I get the following error. Also I am unable to create a new task unless I use the wizard. Does anyone have an idea on why I would be getting this error and how to resolve it?

I am recently new to SQL and any help would be greatly appreciated.
