I am interested in utilizing your CVB SDK, but I want to do so legally. I currently have 2 Teledyne Dalsa C4030 camera, but the license manager does not detect them as valid for the license. I am willing to purchase another camera, or pay a license fee. However, my 3 emails to Stemmer and CVB have gone through without response. Please advise.

We are sorry for the trouble. Thank you very much!
