I sent you a PM but posting here as well. I paid for some things from Martin at AJP also. He has stopped replying to my e-mails as well. Last I heard from him, he had trouble receiving some of my payments through PayU so he was making a PayPal account.
He seemed very knowledgeable and was even looking into sourcing a CIC retrofit for me from someone else.
This was the last message I got from him on Jan 21:
Shipping is arranged for you, sorry for delay i'm out for a biztrip till 23th.
Will get back asap to you, thank you.
