Installed EV3 software on Win 8 and it won't load EV3 software used to work on my laptop.  Now it does not load any more.  When I double click on the LEGO Mindstorms icon.  It starts the procedure of loading the software.  Then it stuck there and won't go further.  I tried to remove the software and reinstall it.  Nothing helps.  Has anyone else got into this problem before?
A possibility is, that you lack the latest Silverlight update.

I had this problem on some Windows and Mac OS X machines recently.

Maybe you can try to install the latest version: https://www.microsoft.com/silverlight/ I think it's worth a try.
