Well, I am new unity3d 5.3 ,I don't know that why I am getting this error when i am trying to enter into playmode

Error is this–
m_CurrentEntriesPtr == NULL || !m_IsGettingEntries
UnityEditorInternal.LogEntries:GetEntryInternal(Int32, LogEntry)
UnityEditor.DockArea:OnGUI()
Please suggest how to fix this problem

I might be wrong, but if you notice there is a (Pro Only) in your error and you are using the Unity free version (look at the top bar, it says Unity Personal). this might be the cause of your errors as your version can’t support the assets you are using .
