Hello i am having trouble opening Canon Raw files in Lightroom on a Mark3. I have a NIKON never no problems but now crazyness. I downloaded the converter for light room 4 but still no go. In Lightroom it sees my card reader and card but will not let me import so what do i have to do to get this going hope it is a easy fix.

How we should know that? you don't say anything about the exact LR version and youir camera.
I think you mean the 5D Mark3. This camera is supported since version 4.1.
Try to copy files from your card to Desktop. Then check if you are able to import..
