Edit Original Not Working

Hi All, I use the Edit Original feature to bridge the gap between Premiere and After Effects as a fundamental part of my work flow. It's great as it allows me to edit in Prem and very quickly make any VFX changes in After Effects then re-import without having to worry about opening the original comp from AE. However, where I used select the clip in Prem / click Edit Orignal and let AE automatically open up the spourec project for me to adjust it now opens the clip itself in VLC Media Player. It's a real pain and I can't find how to change the settings back. Anyone got any advice? Many Thanks in advance, Will
