I am using Solidworks 2014 SP2 on windows 10. For some time, I was not able to use Toolbox and some Add-ins. Then I found it was due to a Windows update and modifying the registry would fix that(mentioned in the forum). But now, the add-ins are loaded but the workspace won't load. It shows a grey screen with Solidworks logo. Even if its a new part/assembly or an existing part/assembly. How do I fix this. Please help me with this as I have a project going on and I need SolidWorks most of the time.
