>> I don't know that this is sufficient. The version of the code you imported was GPLv2. They've updated the code since then and changed the license. I don't think you can just take the old code under the new license, more permissive >>or not.

Hi Matt,
	Our code is heavily modified to the original code.
	We have checked when the code was relicensed to BSD, it was almost identical to the original GPLv2 code we derived.

Thanks
