help me to solve the problem, downloading but no speed!!!!

Your posting seems to be getter closer to the right section you should post in. There's many reasons you might be having speed issues.

Do this test: Bug Report instructions & sample image Is the result True/False?

Try deleting your LW Preferences folder whilst LW is closed; instructions here: Fixes for Limewire

Can you give us a total desciption of your set up:
1. OS version? (eg: Windows 98)
2. What firewalls you have?
3. ram?
4. Hard Disk space available?
5. Connection type? (eg: dialup, broadband, cable, etc.)
6. Modem & router brand name & model numbers?
7. Where are you trying to connect from (home, school, work, etc.)?
8. What version of Limewire (LW) & Java do you have? (Go to LW's menu Help>About LW...) Will show both LW & Java version.
9. Who is your isp provider?
10. Is this a your 1st try at LW or is this a new problem with an experienced user.
