I'm having a similar problem to the one above. When I click to load Limewire Pro 4.8, the normal box comes up but instead of the loading bar it goes white straight away and then when the usual search engine would fully load up, it stays white. I've had this problem before when I had the 5.4 ATI drivers installed but once I updated them to 5.5 a few days later the problem was fixed. I recently installed the 5.7 ATI drivers and updated and installed Java. Could this be the problem again? or is there something else that might have caused this?
