Believe I may have found it. Just a beginner error. Opened "Edit Splits" and found there was an Activate button for Auto Splits just below the Start Timer At. (if anyone else is silly like me)

Hiya, apologies if question is silly, Having trouble getting the auto splitter to work. it loads all the splits in livesplit but the Auto part doesn't work. Looked up some tutorials but none of them seem to actually work either. ie, adding scriptable autosplitter in the layout editor as that doesn't recognise the filetype.

Am I missing something? Appreciate your time.
