I have a serious error recently occured at home. When I open the current project I have been working on, on the status line is red and has the message 'error' on it. My character is still visible, occassionally I can access the pull down menus but I cannot access the space bar menus, also the buttons on the LHS such as manipulator tools are redunadant. Any ideas, please don't say I have to restart this project as it's been weeks in the making
