I just got these two "error messages".

What about it?

An error occurred during AJAX Response parsing.
The error response will appear in a new popup.


objErrorWindow is null
on line number 795
in file http://cdn-images.chesscomfiles.com/assets/js/qcodo_all.js

What browser & version are you using? I would also try to be a little more descriptive with the error. For example, what were you doing exactly at the time the error(s) occurred? Did you just click the button to launch the tactics trainer? Were you using it for x amount of time and then it errored?

Hi,

I use mozilla firefox, newest version. I was't using the TT long when it occurred. It happened after i made my first move, the computer didn't move anymore, the time stopped running and suddenly the errors appeared.

I'm getting the same error virtually every time I use the Tactics Trainer on a problem that's longer than one move.  I've been granted a diamond membership for a week, but it's practically useless, since the TT isn't working in this way.  Please help!
