If you want the tracks to play online, use the files only from the Wem folder. Tracks should work fine. If you installed upk files from Packages (besides GFx), then you can not connect to the server. What does it mean "I can't tell if it's working or not"? Music is not at all, or you do not know how the original music sounds? If the music that is playing does not resemble the original music, then everything works. The instructions say that the information about the tracks is contained in the file "Register_Game OST.xlsx". Look there. If you do not have the opportunity to open this table, then use some kind of online services to view the xlsx tables, such as this https://sheet.zoho.com/sheet/excelviewer

I got it working now. It was just an error on my part

I noticed the list does not have the full tracklist for your songs. I only say this because I'd like to get some of the dw songs but you only have the dw7 one listed in the spreadsheet. Do you perhaps have an updated tracklist? Thanks
