Today after my Windows PC reboot, I got attached pop up saying it's processing of "loading ontology changes", but it's not stopped, and nothing response either "Hide" or "Cancel".
There's error message shown in the protege terminal:
Code: Select all

Before I have to load my latest backup, which means I'll lose one full week's work, is there any hint to help me fix this error?
Thanks greatly,
Xiaoqi
