Every form of testing or running project fails

This is very frustrating, and is making my Construct 2 package worthless.

Every time I test I get this message in the latest version of Chrome:

"This webpage is not available

ERR_CONNECTION_TIMED_OUT"

That is after a long, unbreakable loading bar.

I have a full, licensed version of Construct 2, personal edition.

I have run every step in this tutorial:

And this tutorial:

I have almost zero code in my game, just an object with platform behaviour on a tiled backdrop.

I have tested my HTML5 compatibility and gotten a score of 526 OUT OF 555 POINTS on HTML5Test.com, and a similar score for Firefox. I have tried both browsers. I am on a Samsung laptop using Windows 7 and have no problem running any html5 programs apart from my Construct 2 stuff.

To see if it was just the test mode, I uploaded the game to my google drive and ran it from there. I got a message stating: "Your browser does not appear to support HTML5. Try upgrading your browser to the latest version. What is a browser?" - this message only comes up for Construct 2 projects, I clearly have HTML5.

Nothing works. Is there anything that I can do that isn't covered in the above tutorials, or should I just shelve Construct 2?

you have the latest version of google chrome and mozilla firefox? try to update your browsers and see if the problem fixed

I will do that, they were indeed up to date, but I wonder if there was a version issue. I'll test that.

In case anyone is wondering, I tried different versions of Firefox and Chrome, no dice. I switched computers, no dice. Finally, I switched to a third computer, and that seems to be working for the moment. I did not figure out the problem, did not solve it, but I can do my Construct stuff on another machine, so that should suffice.
