DrawCursor GUI problem

After converting my project to Unity 3.4 and clicking on a textfield GUI element I have thi error:

MissingMethodException: Cannot find the requested method. UnityEngine.TextEditor.DrawCursor(System.String text)(at c:/BuildAgent/work/842f9557127/e852/Runtime/Export/TextEditor.cs:819)

How can I solve this?

Hey, go into your Unity projects folder, then backup a copy of your project.

Then uninstall Unity, and download the current version from http://unity3d.com/unity/download/

Hope this helps, if not, comment back!!!
