Castle link with my V2 MMM dead?

[ptt81]

Well I got V2 MMM and just about to get it setup and I couldn't get the link to work...GRRR! It it always red when connected to the PC and does not show in my computer devices, i've try all possible things, got latest link software too 3.11. Could the link be bad? do castle replace it for free? talk about bad luck, but for one the link is bad and not MMM...hhehe
