Ok it's working now, apparently there's some "secure" feature..
This could be a problem with the secure mode. Please try the following steps to disable it:
a) Press Ctrl + Alt + F12.
b) Press connect button on the receiver.
c) Press connect button on the keyboard.
d) Press the escape key.
No idea what it does but it's working now lol. Thanks a bunch guys for the help. Hopefully I don't encounter another problem!
