Unfortunately Google have decided to stop supporting Silverlight which is the tool we have written our MC³ portal in. This means that the MC³ portal will no longer work in Google Chrome.
It does still work in Internet Explorer and Safari (for now). We are looking to re-develop the MC³ portal in a language that will work across all browsers, and will update when this progresses.
The same issue will affect other tools and sites written in Silverlight such as Sky Player (the tool used for watching Sky TV online).
More information on Google cutting Silverlight support in Chrome can be found here;
GOOGLE IS MOVING ahead with plans to kill off support for Microsoft Silverlight in its Chrome browser. The Microsoft runtime depends on an ageing plug-in protocol called Netscape Plugin Application Programming Interface (NPAPI), for which Google is currently phasing out support in its browser.
