Can't unlock K660

Hi there

First time I've used software like this so a total novice. Tried to unlock K660i but D-Ultimate Unlocker doesn't seem to recognise my phone. I've tried everything - holding 2 and 5 whilst plugging it in, with and without SIM etc. Nothing works. I'm connecting via a USB cable. ANy thoughts?

The program is stuck on:

Code:

11:21:50 D-Ultimate Unlocker v3.07 by Cruiser Team 11:21:50 - Fast & Full - Unlock, Relock, Show codes, Sec.zone rebuild, EROM repair, CID change 11:21:50 Initializing... ! 11:21:50 1. Please see the documentation first (the tab 'Info' or attached .pdf file) ! 11:21:50 2. Choose the phone model ! 11:21:50 3. Select the desired options ! 11:21:50 4. Please connect the phone either via USB while holding 2-5… ! 11:21:50 - or via a serial cable and double-click on it in the device list

Any help greatly appreciated!

:)
