Sound Forge - No Recording Levels! Pls Help? Tks!

[tanktank]

Hi there, used to be able to record audio into sound forge but have been experiencing problems for quite a while (i.e. no recording levels indicated by the meters)

My software and hardware seem to be working and tried reading the guides but didn't seem to help. Tried adjusting some sound forge options but unsure...can someone pls advise? URGENTLY need to record stuff. Thanks in advance!

P.S. - Playback of MD track when line-in to PC is fine but recording is not. Checked my audio and recording properties in PC, they're on.
