Hello again :-)
That particular pid you're after is already inside
my radio.cache, as demonstrated by:
=============================
C:\Program Files\get_iplayer>get_iplayer --type=radio pid:p050hczf

Are you sure you did perform a radio.cache rebuild, too?
Won't hurt to retry:

get_iplayer --type=radio -f --refresh-limit-radio=30 --force --index-maxconn=10

optionally followed by

get_iplayer --type=radio -f --refresh-future --force

Other than that, I fear I'm out of more ideas...

Cheers
