Hmm, might have to check the logs to see what is going on. All I can say is that the RegEx is in the correct format. Once it starts getting into MCEBuddy, I’m less of an expert.
As far as I know, the RegEx portion is supposed to correct the lookup so that it can match with IMDB. Then if you have that checkbox checked, it should create it in the folder structure after the conversion without the year since IMDB doesn’t present the year.
