Not able to run bots, Uipath says Licence Expired

Hi, I am not able to run any bots as Uipath keeps saying my licence has expired. On orchestrator it says the same. I was recently using enterprise version trial but later switched to community edition. When my machine is connected through Uipath assistant it shows as “Connected Unlicensed”. How can I change my enterprise licence on orchestrator back to community licence. I am using Uipath studio pro 2020.6 Community Licence.

on orchestrator it shows me this!
