...has not been working for me for a couple of days now. Any ideas on getting the new manifest locations would be much appreciated.

Only the HD streams have disappeared. You'll get lower quality streams until the next release.

For those who might want this before the next release, the current PC manifests are at:

"http://a.files.bbci.co.uk/media/live/manifesto/audio_video/simulcast/hds/uk/pc/${cdn}/${ch}.f4m"

where

${cdn} is 'ak' or 'llnw',

and ${ch} is one of:
