I recently upgraded a 4.9.0 installation to 5.4.9 and I purchased a 5.4.9 lic to activate. The 4.9.0 lic will deactivate. When an attempt is made to activate a 5.4.9 lic, the previous 4.9.0 lic populates in the activation code fields when the activate button is pressed. I have backed up the configuration and uninstalled all versions of visual cron and then reinstalled 5.4.9. After doing all of this, this issue remains constant. What should I do?
