Just a quick note: a useful fix for those working with Articulate presenter and are upgrading to the Flash 10 player.
A couple of months ago I wrote a post about a combination of Articulate presenter, Captivate, Camtasia, social media incorporation and a high definition webcam. It was a quick mash-up, but it resulted in a useful combination of tools that simply look cool.

But when the Flash 10 player came along, that presentation no longer loaded in my browser. This was due to a swf file that was not correctly decodable by any of the browsers that used the new Flash 10. Luckily Articulate came up with a solution, the Flash updater for Articulate.
For all of you that are experiencing the same problem (articulate presenter not loading in browser after upgrading to Flash10) a detailed problem solving page was written.
After installing the updater for Flash, I scanned my swf-files build by articulate. This resulted in Internet Explorer 7 working again. After this I only had to erase the cache in Firefox 3 and Opera 9.64 and Safari 4.
