No Asio Driver Error

Everytime i try to choose the ASIO audio driver in the config tab (instead of DirectSound) i get the error message “No ASIO driver error”.
Then i have no sound until i choose the DirectSound driver.

I’m using the ASIO2ks driver and it works for everything else but not for renoise.

Asio and render to wave are disabled in the free version. You have to register to get them. Unless you are a registered user?

I’m not registered. So this error is just due to the lack of registration? I don’t want to buy the full version and still encounter this error…
