It seems to have stopped working again, I hope it gets fixed in the future, thanks for reading.

Can you tell me the browser and userscript manager you're using and share the URL of the album you're trying to download?

Please also make sure you have the latest version of the userscript (1.0.26) and try disabling any other extensions/userscripts to see if anything interferes with VGMLoaderX.

I used Brave and EDGE, using the latest version of the extension, and I even reinstalled TaperMonkey, but it kept taking too long to download.

If the download process just takes a while, there's nothing I can do about that unfortunately. Either KHInsider's servers are overloaded, or you should check your internet connection.
