The first thing you should try is unplugging the wireless adapter and plugging it back in. If that doesn't work, try uninstalling the wireless driver (from the device manager. You can find the device manager in the control panel), unplugging the keyboard first of course. After the driver has been installed, plug the keyboard back in and allow the windows 'found new hardware' to install the driver again. The 'found new hardware' dialog is automatic, so all you have to do is plug the keyboard in.
If windows cant find the driver, or has a problem for any reason, you can find your driver at:
and install it manually (it installs like any other software).
If your keyboard is still not working, check for any manual locks that might prevent the keyboard from being used normally. Look for an unrecognized key, a switch, or an LED light that might have a picture of a lock. Unfortunately, I can't pull up any pictures of your keyboard, so I don't know if it has one or not.
You might also want to try another usb device (a flash drive or another usb keyboard, if you have one) to make sure that the usb ports aren't the culprits.
I hope this helps, and good luck!
