Endless loading for a simple query on Excel 2013

Support
#1

I'm trying to pull the data from the Majestic plugin in a row of URLs on Excel 2013.

  1. Automatic calculations turned off
  2. Getting TrustedFlow (for now, one at a time because it already hangs with 1 parameter)
  3. Excel keeps loading endlessly, not even showing what what is doing ( screenshot: http://imageshack.com/i/po5c4lSzp )

I tried restarting, but without success. What is going on? I used this on 2010 and worked nicely, 2013 is really pissing me off.

Thanks
