When I start matlab the current folder window is not appearing and I am getting the following warning:

Unable to create com.mathworks.mde.explorer.Explorer, for details see C:\Users\CZQFQP\AppData\Local\Temp\MATLABDesktopCreateError.log

The contents of the log file are as follows:

java.lang.NullPointerException at com.mathworks.mlwidgets.explorer.ExplorerTableConfigurationSerializer.findMode(ExplorerTableConfigurationSerializer.java:186) at com.mathworks.mlwidgets.explorer.ExplorerTableConfigurationSerializer.loadGroupMode(ExplorerTableConfigurationSerializer.java:90) at com.mathworks.mlwidgets.explorer.ExplorerTableConfigurationSerializer.load(ExplorerTableConfigurationSerializer.java:72) at com.mathworks.widgets.grouptable.GroupingTableConfiguration.<init>(GroupingTableConfiguration.java:152) at com.mathworks.mde.explorer.Explorer.buildTableConfiguration(Explorer.java:317) at com.mathworks.mde.explorer.Explorer.<init>(Explorer.java:158) at com.mathworks.mde.explorer.Explorer.getInstance(Explorer.java:887) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.mathworks.mwswing.desk.DTClient.createComponent(DTClient.java:280) at com.mathworks.mwswing.desk.Desktop.createClientComponent(Desktop.java:5536) at com.mathworks.mde.desk.MLDesktop.createClientComponent(MLDesktop.java:709) at com.mathworks.mwswing.desk.Desktop.createClientComponentWrapper(Desktop.java:5551) at com.mathworks.mwswing.desk.Desktop.setClientShowing(Desktop.java:5926) at com.mathworks.mwswing.desk.Desktop.setClientShowing(Desktop.java:5913) at com.mathworks.mwswing.desk.Desktop.restoreLayout(Desktop.java:5061) at com.mathworks.mwswing.desk.Desktop.restoreLayout(Desktop.java:4791) at com.mathworks.mde.desk.MLDesktop.restoreLayout(MLDesktop.java:1160) at com.mathworks.mwswing.desk.Desktop.restorePreviousLayout(Desktop.java:3728) at com.mathworks.mwswing.desk.Desktop.initMainFrame(Desktop.java:259) at com.mathworks.mde.desk.MLDesktop.initMainFrame(MLDesktop.java:542) at com.mathworks.mde.desk.MLDesktop$Initializer.run(MLDesktop.java:850) at com.mathworks.jmi.AWTUtilities$Invoker$5.runWithOutput(AWTUtilities.java:481) at com.mathworks.jmi.AWTUtilities$Invoker$2.watchedRun(AWTUtilities.java:397) at com.mathworks.jmi.AWTUtilities$WatchedRunnable.run(AWTUtilities.java:360) at java.awt.event.InvocationEvent.dispatch(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)

And when I try Start-> Desktop Tools-> Current folder I get the following errors:

I can see its a java error but I don't know how to fix it. I have already reported this issue to technical support but I wanted to see if anyone has had the same issue and can shed some light on the situation.
