tc electronic konnekt 24D not connected to my macbook pro

i have installed TC Near software and the driver for konnekt 24D from the CD. it has been asked to update the driver during installation but the link is corrupted. after finishing the installation i have restart my mac but it says that the device is not connected. i have changed the cable because the fireware light is not on but the problem doesn't solve. how can i download the latest driver? there is no anywhere in the whole internet to download the driver for TC electronic konnekt 24D interface driver or the TC Audio interface software. please kindly tell me how can i solve this issue and from where i can download the latest driver and software.
