Visual Studio 2012: Crashes on loading project

My Visual studio 2012 kept crashing while loading the project. Acessing the Activitylog.xml from C:\Users\rmanni\AppData\Roaming\Microsoft\VisualStudio\11.0\ActivityLog.xml, referred to the following error

Type provided must be an Enum.
Parameter name: enumType




I wiped out the following folder, and launched Visual studio again, It reconstructed the cache, and everything is good now.

Just delete all the contents from the following folder. Replace rmanni with your user name

 C:\Users\rmanni\AppData\Local\Microsoft\VisualStudio\11.0
