IP Designer Error

When trying to open IPDesigner, we ran into this error:


Opening the log reveals a java.lang.StackOverflowError:


This error was fixed by going to (C:\IPDesigner\ADTALEMPRD\workspace\.metadata\.plugins\org.eclipse.ui.workbench)
And removing workbench.xml. We opted to rename it to workbench_old.xml and when we restarted IPDesigner, it generated a new workbench.xml and started working correctly.
