Can you delete this 0.snap file and try again? Its location is: \config\.metadata\.plugins\org.eclipse.core.resources\0.snap

Thanks.

The problem is strange. I solve this by reinstalling…

I tried deleting the “Snap” file but this did not fix my errors. I reinstalled and the errors no longer occurred. Thanks for the assistance above.
