Instead of posting and waiting for a response you should contact Randy Pike directly as he is the Primary contact for all things Tekin and is actually quite active on the Tekin boards. Drop him a PM and he will get you squared away. I've spoken with him several times and he has always taken care of me.

Realize how many people post on the Tekin thread on any given day and you'll understand the delay in answering your question. Good luck with it!
