UrBackup Server - how to uninstall???

[WTF]

how do i get the app uninstalled?
i've deactivated the app and after hiting delete and ok, nothing happens and the dialog field still appears!

when i try to delete the shared urbackup folder it's not possible cause it's used by urbackup (error 5033), so i think the server is still running.
but how and where can i stop it?

thx alot

Mine is just fine (the lastest version). I guess it's caused by some clients are still working. Anyway, you'd better to report it to asustor directly.
