Lego Starwars "Quest fot R2-D2"

My son used to play "Quest for R2-D2" in the Star Wars section of the web site but for a reason that we can figure out, he can't any more. From a month or so, he keep getting this messages:

"Unity Error launching Unity Player"

or

“Unity The content was stopped because a fatal error has been detected”

We have downloaded a software that the website asks but with the same result after the installation. We use Mac OX 10.6 and we have try with both Firefox and Safari with the same result, but before he used the same Mac with the OX 16.6 to play for hours.

We hope you could help us, guide us to fix or update our computer so he can play again, and if it's something about your website compatibility with Mac or Firefox or Safari, we sure hope you can do something to make it more universal.

We look forward to your answer, thank you!

While burnumd's comment is correct, this site is for Unity developers and not for end-users, the problem you are seeing is probably related to a bug Apple introduced in their latest update to QuickTime, shipping with OS X 10.6.6. Downloading and installing the latest Unity Web Player from http://unity3d.com/webplayer/ will probably fix it.

Sorry, but this site is for questions related to authoring content using the Unity game engine. You'll need to direct your questions to the developer of the game (which I believe is Three Melons, whom you can contact here). They may direct you to email support@unity3d.com if the problems are with the Unity web player itself rather than their game or the site.
