Acess Effects in Cubase Vst 32

Hi…Can anybody help…I’m using Cubase Vst 32 and unable to access the effects after 10 years of use…Once I’ve opened the software and opened the Vst Channel Mixer 1 and then try to access the effects in the Vst Channel settings drop down box I get a “No Effect” option ,where I should have a list of effects to choose from…I’ve reinstalled the software with no change.Any ideas…Thanks…
