VLC is unable to open the MRL 'file:///C:/Users/Lenovo/Downloads/%5BEnglish%5D%20%5BTouhou%20Vocal%5D%20%5BButa-Otome%5D%20Utakata%20%28spanish%20%26%20english%20subtitles%29%20%5BDownSub.com%5D.srt'. Check the log for details.
I think I press something back then, but after googling and tampering for weeks I still don't know what exactly.
