Hi. texasbek told me you were having troubles with LJ too. Not sure if the troubles you are experiencing are the same as mine were and I'm really not good at this type of thing but I thought I'd just point you to the place I found that helped me out.

There's one note for Mac users. I just followed the instructions there and Voila! my problems were over. Maybe this will help you too?
