The queries you metioned work on the example files:
http://www.wolframalpha.com/input/?i=basic+properties&examplefile=1&fileinput=FileUpload%2FBowTie.gxl&examplefile=1&fileinput=FileUpload%2FBowTie.gxl
I'm afraid the most likely answer is that the file is too big and Wolfram|Alpha won't work with it.
If you want to work with larger files, your best bet is to use Mathematica online:
