full error: "license information for this component not found. you do not have an appropriate lisence to use this functionality in the design environment"

I recieved this error when I tried to use a control which i previously downloaded and registered. I found a thread which recommended I use a program off the VB disk (http://www.vbforums.com/showthread.php?t=49499). Trouble is I haven't got the disc, and cant get hold of it.

any ideas anyone?
