I have problems with Cubase 5

I have Bias FX, and I my Cubase 5 can’t recognize it. The Bias FX works and does effects for my guitar, but I can’t find it on the Cubase plug ins
And I also have lexicon alpha, and for some reason, my Cubase 5 can’t recongnize the instrument either. My computer gets the sound from my guitar, I checked in the settings, and I hear the guitar through the headphones, but the Cubase doesn’t get any voice. I can’t record my guitar

Hi and welcome,

Might be the plug-ins are blacklisted, because the plug-ins are unstable. Check the VStPluginsBlacklist.xml file located in %AppData% Steinberg/Cubase 5.
