You said, "there is no button on the controller box. But I think i can connect the box to my cases reset button though it would be a bit of a hassle". Yes, DO THAT. Commonly, you connect a cable supplied with the box to the pair of pins on your mobo's Front Panel header where you normally have plugged in the two wires from your case's front RESET pushbutton. Polarity does not matter for these two wires. This means you no longer have a Reset button. BUT that front button IS the way you can change your light display manually. NOT having done that is why you can NOT change your lights now.
Once that is done and working AND you have also connected another supplied cable from the Controller box to your mobo's JRAINBOW1 header on the bottom edge near the front (see your manual, p. 25 and 39), try the long press on the Reset front pushbutton. It may switch to control of the lights using your mobo. Now, to get THAT to work you will need to install (from the mobo's DVD disk) the MSI utility Mystic Light.
