The perspective one should be fixed within the next few nightlies - see [http://forum.inductiveautomation.com/t/perspective-missing-in-the-designer/21743](http://forum.inductiveautomation.com/t/perspective-missing-in-the-designer/21743). The serial one is interesting - I’ll see if I can reproduce locally. ---

If nothing else, the builds should be the same. Could you get a .gwbk, uninstall, reinstall, then restore and see whether it’s working? I can’t reproduce the issue with the serial client hook not loading. ---

I think that should be sufficient - thanks for your help, and glad you’re up and running. ---

Hello, I’m currently in the process of migrating several modules from 7.9 to 8.0, and I ran into a similar error as Brian. Prior to Christmas, we had already migrated several modules from 7.9 to 8.0 on an older nightly build. They remained on our dev servers running without issue into the new year. Recently, I updated our dev servers to the 2019011602 build, and the following stack trace appears when I launch the Designer: com.inductiveautomation.ignition.common.modules.ModuleLoadException: Hook class “com.kymera.twilio.designer.DesignerHook” not found for module “Twilio Notifications”. at com.inductiveautomation.ignition.designer.IgnitionDesigner.loadModules(IgnitionDesigner.java:753) at com.inductiveautomation.ignition.designer.IgnitionDesigner.startup(IgnitionDesigner.java:452) at com.inductiveautomation.ignition.designer.DesignerStartupHook$2.run(DesignerStartupHook.java:313) at java.desktop/java.awt.event.InvocationEvent.dispatch(Unknown Source) at java.desktop/java.awt.EventQueue.dispatchEventImpl(Unknown Source) at java.desktop/java.awt.EventQueue$4.run(Unknown Source) at java.desktop/java.awt.EventQueue$4.run(Unknown Source) at java.base/java.security.AccessController.doPrivileged(Native Method) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(Unknown Source) at java.desktop/java.awt.EventQueue.dispatchEvent(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.desktop/java.awt.EventDispatchThread.run(Unknown Source) Caused by: java.lang.ClassNotFoundException: com.kymera.twilio.designer.DesignerHook at java.base/java.net.URLClassLoader.findClass(Unknown Source) at java.base/java.lang.ClassLoader.loadClass(Unknown Source) at java.base/java.lang.ClassLoader.loadClass(Unknown Source) at java.base/java.lang.Class.forName0(Native Method) at java.base/java.lang.Class.forName(Unknown Source) at com.inductiveautomation.ignition.designer.IgnitionDesigner.loadModules(IgnitionDesigner.java:750) … 15 more Ignition v8.0.0-beta0 (b2019011802) Java: Azul Systems, Inc. 11.0.1 This occurs for any module using a Designer hook. I also updated to the newest nightly build today, with similar results. Any support with this would be appreciated, thanks. ---

These are our own modules, so 3rd party. The modules that come packaged with the nightly build don’t appear to have this issue. [Next page](https://forum.inductiveautomation.com/t/bug-got-this-error-after-reinstalling-nightly-change-this-morning/21765.md?page=2)
