Hi Tom,
I have found the reason for autolearn error 62, though can only assume there must have been a save issue somewhere during the upgrade and next run stage.
I found that the correc.txt file was not line format structured as it normally is. eg seemed to be centred vs left aligned with line breaks.
Any way lucky I had previous day backup, so added recent day line to old file and all ran perfect.
So now running new version no issues.
Strange about the iteration issue as I have been running at 60 for months now (just to see if it would differ or break) I like doing that.
Kind Regards,
