Hi,
I am hoping someone might be able to help me (I hope this is the right place to ask for assistance if not I apologize)

Whenever I try to export any runnable Jar file I instantly get

"An error has occurred. See error log for more details.
java.lang.NullPointerException"

The error log contains
Problems occurred when invoking code from plug-in: "org.eclipse.jface".
java.lang.NullPointerException at org.eclipse.jdt.internal.ui.jarpackager.AbstractJarDestinationWizardPage.validateDestinationGroup(AbstractJarDestinationWizardPage.java:239)

Unhandled event loop exception
java.lang.IllegalArgumentException: Path for project must have only one segment. at org.eclipse.core.runtime.Assert.isLegal(Assert.java:66)

The programs do work and I can export them on a different computer. I am at a complete lose as to what may be causing this.
I would appreciate any assistance.

Thanks in advance!
