Need some help!

i went to export it, but the export button was grayed, i tried to click new and it said if i would like to save my room and i clicked yes, but nothing happened, the only thing i could click was merge and i can only save it as .3dw, when i closed 3d world studio, i get this error message:

i reopened the program but it wasn't still working, so i need some help fixing 3d world studio.
This profile's been around for nearly eight years
