According to: http://www.microsoft.com/nz/hardware/mouseandkeyboard/ProductDetails.aspx?pid=120&active_tab=systemRequirements, you need to be online to setup the software. Was that the case? If not you need to uninstall the software and then get online and install it again while online. You may want to download updated software rather than use what came with the device - but that's your choice (though it is what I would do). Here's where to get it:http://www.microsoft.com/hardware/download/download.aspx?category=MK.
You can try Microsoft Support but I don't know if it will be free and can't tell without yor product identification number. Here's where to start:https://support.microsoft.com/oas/default.aspx?&c1=502&gprid=15022&&st=1&wfxredirect=1. You will be told if charges apply before they charge you.
I looked up your keyboard and there is no online documentation availalble to assist with installations or problems or anything (just technical specifications). Your best bet is to uninstall whatever you've installed at this point and start over fresh with a new software download and making sure you are online when you install.
I hope this helps.
Good luck!
