cant restore trayagent

hello dear hercules dj mix room-community :)!

after my dj control air arrived, i installed the latest drivers and with them, the trayagent. in the configuration-menu i disabled the option to display the icon in the systemtray, but now i want to restore it but i cant find anyway to do so. i checked the autostart-option in the system configuration (msconfig), checked for configuration-files or not-running services. even starting hdjseries2traybar.exe manually just starts the control panel. after reinstalling two times and deleting the previous entrys in my registry, the trayicon still wont show up...
is there any way to restore the trayicon again?

thank you very much ,
