Good day, I paid a subscription for 3 Parallel's Toolbox for a year, but there is only 1 License Key on my account. When I try to activate Parallels Toolbox for the second computer, I get the notification that the license is already in use, and that I must remove it from Computer 1. Hence, I cannot install on Computer 2, let alone on Computer 3. My reference number is: 277525487. The Facebook solution didn't solve my issue either (KB article https://kb.parallels.com/en/123509). Thanks a lot!
