new version 3.1.0 jdk error

Hi, I've updated to the new version of Mendix 3.1.0 and keep getting the following error: Unable to start the server, because the installed JDK version is not compatible. Please install a compatible JDK version. See the 'System Requirements' page of the reference guide for more information about supported JDK versions. I have updated the jdk version as per link supplied and restarted, mendix, then also restarted box and still get the error? Anything else I need to do to be able to build the app? It worked fine this morning just before I updated to new version. LR.
