Just an update... I sent a support query to Logitech via its website on Monday (date of creating this thread) explaining that I can not order a new receiver online as they only ship to the US and Canada and a few others. I got a reply from EMEA support staff saying that they have ordered a receiver from the warehouse and that they will ship it to me soon. On Friday UPS delivered the receiver.
How awesome is that?!?!?! They sent me a new receiver via courier for free! Aboslutely epic support!!! Thanx Logitech, you have a customer for life.
