Its not because you haven't downloaded pro, I have and continue to get the same message everytime I install and reinstall both limewire and Java. I have checked my firewalls etc. One thing I read is that mcafee has a bug in it and sometimes that prevents the success of limewire working. I am hoping you get a response so that we'll both benefit, but frankly I am getting a little impatient. I want my money back if this continues to happen. Good luck and if you read anything that is benefial to us both let me know.
