Try spooling the ribbon manually in one direction or the other for a foot or so to get to ribbon that's not dried out and you may be in luck and not need to replace it right away.

If you've got the original Remington metal hubs (which are needed for the auto-reverse functionality), keep those as they're expensive to replace. Spool your new ribbon (1/2" wide and typically comes on 2" diameter plastic universal spools) from cheap plastic spools onto your originals.
If you don't have the original metal hubs, you can call around to repair shops for replacements (which may be the cheapest route) https://site.xavier.edu/polt/typewriters/tw-repair.html. Ribbons Unlimited also sells these hubs with ribbon attached, but it's more expensive to do this, but once you've got them, you can buy ribbon by itself for much cheaper in the future and just wind the new ribbon onto existing spool hubs.
Here's some useful videos which might help you out in terms of how to spool up your ribbon:<br /> - https://www.youtube.com/watch?v=iTFM54VKKc4 (Slightly different model to yours, but same spool mechanisms) - https://www.youtube.com/watch?v=xWQTa4b7jPs (This one has some advice about using a Remington without the spools.)
