The mcebuddy service is unavailable

I am unable to locate mcebuddy logs. when I click on “logs” nothing appears, when I click on “events” I get a window with:
error retrieving event logs, unable to get event log entries from the mcebuddy engine, retrieving event logs from local machine. This displays much info but I don’t know where the file is that contains this info. I did a C drive search for mce.log with no results.
My environment is Win 10 using NextPVR with HomeRun OTA tuner boxes to record shows as TS files, which MCEBuddy then converts to Mpeg during inactive recording hours. I have been using this for many years without issues. When MCEBuddy stopped connecting to the service I did an upgrade to 2.6.x from 2.5.x, however I failed to do a an uninstall, so I followed guide to remove all file before doing a clean install.
