6.5a3-hardened Tor Browser error: 'could not connect to the tor control port' permissions issue??

Ubuntu 16.04

I used to run 6.5a2-hardened successfully from external media without problems, as soon as the update came through, i am no longer able to run it on external media. Only when extracted to Ubuntu desktop will it connect successfully. Im pretty sure this is a permissions error.. please help? When i extracted the previous version to external media i never had any problems.
