Why are licenses rejected even though they are running?

Last subscription day or relocked license? If first, I still did not fix the issue when due to time zone difference subscription end is counted differently on macrolab server and your PC. If second, bot will check state of the license from time to time and if license was reused with different account, first instance will expire. Relock function was implemented to switch account in case of a ban, but not to clone your license several time.
