I prevously used Kazaalite 2.4.2. I had many download problems. My downloads were very slow and most of the time i could not even find users to download from. I then uninstalled Kazaalite 2.4.2 completely.
I then installed Kazaalite 2.1.0. When i installed Kazaalite 2.1.0 i ensured that i deleted all registry from the previous Kazaalite.
Everything works fine now. I get my normal download speeds and connect to heaps of users.
This has been working for me for ages now and i hope this helps some of you guys solve your Kazaalite downloading problem B)
