some weirdly formatted SSA file that the system doesn't recognise... can happen sometimes unfortunately, subtitle is now disabled and won't be fixed.
Also, could you check what's going on with subtitle with file_id 6972559? The download url returned by /api/v1/download returns an empty response
oh don't worry about this, debugging is my life. Also, I could fix a little bug while tracking your downloads, so was a helpful post !
UPDATE 2
Ok the links seem to work now, so it was my mistake. Sorry for wasting your time and thanks for your help.
yes, just saw that you did, and updated your username as requested
Thank you. I still want to change my username on the old site. How do I do that? Contact form?
