The guy hasn't been seen since July 19 so I doubt he will answer you. It looks like it is not a launcher problem so we likely can't help you. Try updating your graphics drivers and googleing the issue.
I will think of adding this issue to the Common Problems and Solutions sticky update because I have seen a few people who needed to update their graphics drivers
Thanks for helping and adding some new info, in the future use the edit button if you are making posts back to back. It just makes it easier to read and follow :)
