ERROR: Could not extract a valid PID from ARRAY
Hello -

Tried to refresh radio cache, but to no avail.

C:\Program Files (x86)\get_iplayer>get_iplayer --refresh --type=radio

ERROR: Could not extract a valid PID from ARRAY(0x3676ac4)

C:\Program Files (x86)\get_iplayer>get_iplayer --show-prefs
Options in 'C:\Users\P____/.get_iplayer/options'
        type = radio
        pid = ARRAY(0x3676ac4)
        radiomode = best
        versionlist = original

C:\Program Files (x86)\get_iplayer>

Appears that I've messed up the ARRAY content; is there a means to correct this?

You should not have the line beginning 'pid' in your options file.

Delete that entire line.

Thank you for the response; greatly appreciated.

Could you please enlighten me as to the command line entry I ought to submit to ensure deletion?  Unsure.

Thanks again.
You could delete it manually (open the file in a text editor) or use the command below which might work:

get_iplayer --prefs-del "--pid=ARRAY(0x3676ac4)"

The output you posted here contains the location of the file should you wish to edit it manually if the command above doesn't work.

Success!  Many thanks once more; most grateful.
