1. What McAfee programs are installed, and which version?
-SecurityCenter 7.2.147
-VirusScan 11.2.124
-Personal Firewall 8.2.118
-SpamKiller 8.2.137
-Privacy Service 9.2.134

2. Are you able to identify which McAfee program is the cause of the issue?
No, haven't tried, as it came w/ computer as a trial & I don't have setup/install files.

3. What version of LimeWire (Pro) are you using?
4.12.11

4. What ports have you configured for LimeWire? Does the issue exist if you try different ports?
Default ports, haven't tried reconfiguring.

5. Opening ports in the McAfee Firewall:
Opened Windows File Sharing ports 137-139

Result: Nothing. Same as before.
Will try turning off the Redirector Service next.

Result: Turning off the Redirector Service:
Works perfectly, full bars & good internet connection for other programs.

What does the redirector service do? What are the possible consequences if I leave it off?

Edit again: Restarted the director service, and both LimeWire and other connections still work perfectly. Solves my problem for a little while, at the very least. Thanks for the assistance.
