No sound from Halion Sonic 2

I was trying to use the key editor in cubase to write and no sound came when I wrote the part on a Halion Sonic part. I thought it was a problem with cubase but when I shut down cubase and opened HS on its own and just played the sounds on the HS piano no sound came out.

I am gonna re-connect my UR-22 and see if that fixes it but I used the UR-22 to send audio and midi from a midi sequencer into the computer and therefore into Cubase, assigning different midi channels to different VSTs. I mean, I used it as my sound device for everything basically but I just moved and I figured if I was writing the midi parts directly into the key editor I didn’t need it. I just have my headphones in the headphone jack on the computer.
