UV Snapshot can't be saved. The menu doesn't pop up

[wictux]

Hello,

I have a problem saving an UV snapshot in Maya 2014. Previously I selected "UV Texture Editor"-> "Polygons" -> "UV Snapshot" and after that a window opens so I was able to fix the file name and the file path.

But now nothing happens after choosing "UV Snapshot" and Maya says "No help available for this tool".
I searched the whole computer for a file named "snapshot" or "UV" but I didn't find it.

Could anyone show me how to solve the problem?
Thanks in advance!

P.S. I apologize for the misspellings and grammatical errors. Nevertheless, I hope that you understand what I mean.
