Seems like you have tablet installed on your machine may be Wacom or say and that was being used with PSE. Just uninstall or remove the tablet from your machine and try. Also try this prior to doing that:
1. Close Elements.
2. Launch the Photoshop Elements Welcome Screen and hold down ctrl + alt + shift as you click Editor.
3. Continue to hold the keys until you see a message box asking if you want to delete Photoshop Elements settings file; click Yes. Elements will open with default preferences.
if nothing help try this as well of skip loading of 3rd party plugins by default - http://blogs.adobe.com/pselements/skip-loading-of-optional-and-third-party-plug-ins-in-pho toshop-elements-editor/
