Emergency Problem KNIME Platform V5.4.0 Will Not Allow Nodes To Be Added

All of a sudden, both versions of KNIME I run, 5.4.0 and 4.7.8 will not allow any node from the Node Repository to be dragged into my workflows.

I have restarted both versions several times and restarted my computer. Nothing.

When I try to drag any node in I get the little symbol of the red circle with the red line slashing through the middle.

I’m in a bit of a panic right now.

This is my personal (higher-end) laptop, no firewalls, no special passwords or systems to work through.

KNIME has run fine on this machine for two years; I’ve made no changes. It ran fine two hours ago. My only change was a typical microsoft update. I do not know what they could have possibly done…

When going online, I can drag individual nodes into my workflow from KNIME sources. I just cannot drag any node in my local versions of KNIME into my workflows.

On version 5.4.0 I let the startup prompt check for updates and none were needed.

I’m stuck until I hear from you.
