Thanks for the suggestions! Unfortunately I still need help.
Russ, I couldn't open the stl file directly, but here is part of it after I opened a text version of it:
00:00:00:23 , 00:00:03:07 , Spanish (overwrite English) | Me encuentro con tantos | que anhelan algo más…
00:00:03:07 , 00:00:04:10 , están hambrientos…
00:00:04:24 , 00:00:07:14 , Algunos saben que están | en una búsqueda espiritual,
Steve, I was indeed trying to import by clicking "import asset" as I've always done before. So I tried clicking the S1 track with Ctrl+Click and no dropdown appeared. Tried other keys and tracks also with no luck. No dropdown.
Max, will note your comment for the future but at this time I don't have any file to use that imports okay.
Appreciate your responses, and look forward to more ideas.
Thanks again.
