I am trying to convert some of my 2014 XBOX360 DLC to PC (my 360 is on its last leg), but it does not seem to be working. I copied the file from the XBOX then to my computer. I used the RockSmithToolkitGUI. Converter tab. Selected source XBOX 360 target PC. Selected Cherub Rock (I purchased this). Clicked the Choose DLC to button. Selected the XBOX 360 DLC and clicked open. Nothing happens after this and the Choose DLC to button is not clickable any more. Any ideas? Thank you, Tom
