Windows store app - WWW doesn't seem to be working

Questions & Answers

The docs say that WWW is supported on W8 Store apps:
“Things that are not yet supported:
Network classes, WWW is supported though”

However, i cant get it to work. It works fine in the editor game mode, but on a Windows Store build its not working.
For example this code here:

// Post the URL to the site and create a download object to get the result.
hs_post = WWW(highscore_url);
yield hs_post; // Wait until the download is done
if(hs_post.error) {
print("There was an error posting the high score: " + hs_post.error);
}

Is there something i can do?

But I’m not getting any info from the sites, not even old info.
I tried with the running number but still no luck, it seems im getting an error:
The system cannot locate the resource specified.
This only happens on the store build, works fine in the editor and on windows phone.
