chess mentor serious error... help please...

 *EDIT 2* I was able to move past the lesson using the "skip this lesson" link. So there's no problem I need solved. You might want to see if the lesson is buggy, for future users.

Hi... I've like doing Chess Mentor sequential rather than adaptive... doing Sam Shankland's improve your chess series I hit a lesson where at the end Chess mentor will neither allow me to input a move, nor move to the next lesson, I'm stuck in place. The lesson is (titled, ironically enough, "A total mess"):

http://www.chess.com/chessmentor/view_lesson.html?id=5841

I'm stuck at a screen where the white king is in check and his queen is forked by a N, and the prompt is "all forced, no hints ..."

I'm going to try a work around right now -- starting a new course -- that should hopefully get me out of the cul de sac I'm in... but I wonder if this problem is in the lesson, or if it's just some flukey thing computer thing.

*edit* yeah I could start a new course... but I cannot make progress in shankland's Improve Your chess Course... I'm stuck there.

Oops... at first it worked fine here... i managed to solve and complete the lesson... now it is hanging after i tried to replay it... seems to be an AJAX programming issue

i have the same problem   what is the problem?   maybe u aughtta use comet.lol

same problem for me as well
