Lost a bit on Knowledge Management Systems is KTS the same company only under a new name. Thanks to any one who can help Mary

All i know about KMS was its gone with my money. Who took them over ? I was out of the country for about 18 months and i bought them for long term so i didnt watch them and when i heard that the price was going down i though that they would come back again at some time. but then they just went t.... up and no more news, money gone. Was it KTS who took them over
