Cubase AI8 on imac yosemite 10.10.5 : no sound/vst connections

I’m having a terrible time troubleshooting my “no sound” issue. i create a new project. i import my audio file. then i create new audio track. I’ve successfully recorded before…but I’m thinking something is malfunctioning. first i noticed that the mic was only playing out of one ear. i then googled some things and ended up in the vst connections tab. after attempting to switch things to mono from stereo all sounds stops. i exit out and nothing. I’ve referenced setting from my few successful projects and I’m not noticing any differences. please help. call me [phone number removed]
