Minimwatch error message after update

[janders1954]

I was prompted, and did an update, to MinimServer yesterday (actually, now that I think about it, I'm not sure if it was Minimwatch or Minimserver that I updated). Now MinimWatch isn't working, with a red note icon and error message seen below. Below is the log. I am unable to locate the file "jminim-0.7.115.jar" mentioned in the log.
Any suggestions, anyone?

Regards;

John
