A few days ago I was working on the Crystal Ball Project and everything was going well..... until today. I tried loading up the project like normal, however, I am now receiving a large error code for my Activity_main window.
It says Cannot create extension will hundreds of error code lines. Here is a small portion of this string of errors.
org.eclipse.core.runtime.CoreException: Cannot create extension at org.eclipse.ui.internal.WorkbenchPlugin.createExtension(WorkbenchPlugin.java:296) at org.eclipse.ui.internal.registry.EditorDescriptor.createEditor(EditorDescriptor.java:235) at org.eclipse.ui.internal.EditorReference.createPart(EditorReference.java:318) at org.eclipse.ui.internal.e4.compatibility.CompatibilityPart.createPart(CompatibilityPart.java:266) at org.eclipse.ui.internal.e4.compatibility.CompatibilityEditor.createPart(CompatibilityEditor.java:61) at org.eclipse.ui.internal.e4.compatibility.CompatibilityPart.create(CompatibilityPart.java:304) 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)
If you need any more information please ask. Help so I can continue.

This may be a problem with Eclipse itself where you need to update Eclipse and the Android tools. Check the 2:54 mark of this video for a walkthrough of how to update everything. If you get it all up to date and still have this problem, please paste more error messages in here and we'll go from there.
