Hello
Ive been using lime wire pro for a long time now haven’t had any problems Lime Wire Pro 4.9.24 is far the best ive found ive tried updates from that the search is hasn’t been to good.
I have found , seems 4.9.25 , 4.9.26 , 4.9.27 was getting slower but at 4.9.28 the search hasn’t been good and up seeing if you can look in to it.
I go back to 4.9.24 and down got no problems im running Windows XP Professional Version 2002 I do not have any windows updates on the pc or nor do I have windows service pack 2 installed.
The only firewall im running is Zone Alarm Security Suite v6.0.667.000 and I am on DSL and I do have the latest Java Sun installed jre-1_5_0_05-windows-i586-p
I hope you can look in to it and fix what ever change you done.
