The same thing just happened to me. The service will no longer start with an error code 1067: The process terminated unexpectedly. It seems likely related to the new version of Java (7.11) that just installed with automatic updates. I will try PMS v1.72 and see if it resolves the issue.
Update: v1.72 does not fix the problem. No surprise since this version is prior to the latest Java update.
Does anyone have a fix?
