Cubase 5 information

Hi everyone im new here and i have a question :

When i use Guitar rig 5 and Cubase 5 i open a stereo track and insert GR5(and a preset) when i hit record i can’t see the waves but when i play back the track i can hear what i did
how can i fix it and see the waves?

I’m not really shure if it is available in cubase 5, but try to switch on “show waveform” in preferences > event display > audio.
