Maya :: Error / This Command Requires At Least 1 Argument(s) To Be Specified Or Selected

I opened my awesome camera projection mapping scene and all of a sudden the file doesnt work.I get a popup saying "Errors have occured while reading the scene that might result in data loss. Please check the Script Editor for details."

The Script Editor says:

file -f -new;
// Error: This command requires at least 1 argument(s) to be specified or selected; found 0. //
// untitled //
commandPort -securityWarning -name commandportDefault;
// mental ray for Maya 2011

[code].....

Anyway, I googled it and "delete the mayafolder and restart Maya, thus creating a new mayafolder automatically" came up and so I did, it didnt work. The next solution apparently was to export eveything into a new scene, but only a third of my stuff is IN the scene so that doesnt work at all (yes i tried anyway).The last thing I did in the scene before I closed it down for the weekend, was to import about 10 nCloth flags into the scene. Disabling them all ofcourse, but still, that might be the reason it's crashing, I dont know.
