Sorry for the late response.

I'd avoid TalkTalk if you can. Else only use LW at off peak times.

Try deleting your LW prefs folder found here: /Users/your_username/Library/Preferences/LimeWire

If still problems then try LimeWire cvs builds (4.13.4jum490) & get a nightly build.

Other things to try or be aware of:

1. Setting up Java 1.5

2. SAFE Boot & Repair Permissions which should be done after any installations or updates.

3. Don't share more than about 1,500 files. If they are mostly video files then reduce it a little more.

4. Tip: Purge the Downloads Queue! (click on blue link)
