HELP!!!

I keep getting this message, at the moment only when I open photoshop, no other CC subscriptions apps. I have two identical iMac setups, one at home and one in office. On occassion I have been known to leave my home computer on while I go do something and forget to go back to it and turn it off, so on occassion I would have two Photoshops open at the same time on two different computers, but only actively using one at a time - a bit hard to use two iMacs in two different locations at the same time. Both computers do have the same name.

This message has come up the past two day so last night I double checked and home iMac is shutdown so I am definetly not using the software simultaneously, why do I keep getting this message and how do I stop it.

Thanks Tania
