I installed 3.0.8.0, everything worked beautifully. I double clicked an ISO file, the same prompt appeared that appears when the key is double clicked which says something to the extent of Thanks for registering, restart the program, etc. Now when I start the program, nothing happens. I started Task Manager to watch...the thread starts, runs for 3-4 seconds and disappears. I'm not sure what information anyone needs to help. Just let me know.
