[Pharo-users] Pharo 8. Epicea seems to be turned off. how do I get it working again?

Hi- I had an image lock up so I "Force quit" it from the apple menu. When I check "Code Changes" its most recent changes are from 9 days ago. My most recent save was a few hours ago & I was able to restore the missing code between the save & now by dropping the changes file in the image. How do I double check and get epicea running again in this image? Thanks
