imaginitiveceo,
What player are you using? The LW player's not good, try disabling it (tools > options > player) & using a different player

russian dude,
Have you installed LimeWire? Download from the official site only
Lime Wire » Official Website & Free Download, BitTorrent «
Use the offline installer...when you click to download & a diialog box pops up asking if you want to run or save the file, cancel that. Now use the option to download the offline installer.

After you've installed LW, read through these: LimeWire FAQ and User Guide
