I am trying out LiveCycle server and workbench using the trial software. I've made it to Section 5 of the "Creating your first LC App" tutorial but am getting an error from the workbench. I have tried reinstalling the workbench but I got the same error even after reinstalling. See the error message below which I get when trying to open the process editor (i.e. step 5.6 in the tutorial).
Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.
org.eclipse.core.runtime.internal.adaptor.EclipseLazyStarter$Terminati ngClassNotFoundException: An error occurred while automatically activating bundle com.adobe.ape.core (4).
