I have been using LimeWire for over a year now. All of a sudden, I can't get LimeWire to open from my dock on my Mac. I use Mac OS 10.3. LimeWire appears on my dock BUT when I try to open it, the icon in my dock jumps up and down...YET LimeWire won't even open. This is really bothering me since I can't download anything. Please help me. Thank you.
