I recently bought a Canon Rebel xti, and also a 2GB memory card along with it. I also got a Digital Concepts 21 in 1 card reader. When i plug in the card to the reader an error pops up saying the file doesn't have a program associated to it and i need to create one in the set associations control panel. I know where the set associations panel is, but i don't know how to actually associate a program to the reader. Help?
