Proxy problems?

Hi, I'm trying to use this sw for the first time, since it looks promising :-)

I got the latest version (3.182) and started trying to scrape my movies. Unfortunately I don't get any scraped information. If I go to the change movie page and select correct entry in IMDb I get the following error:

Code:

System.NullReferenceException: Object reference not set to an instance of an object.
  at IMPA.getimpaposters.getimpathumbs(String title, String movieyear)
  at Media_Companion.Form1.Button21_Click(Object sender, EventArgs e)

could it be because I am behind a protected http proxy?

thanks

Does not look like a proxy error to me, although I have not seen the source code. PS: coding proxy support into a VB.Net app is quite straight forward and I would be happy to assist. Is this project open source?
