Wow - simply unbelievable!
Tried the fix that BasRuiter posted under Vista + McAfee 2007 + LimeWire = dropping connection and it WORKED!!! I feel so relieved...how do I thank you two??? This is great!

Here is what fixed my problem:

To narrow down where the issue lies, could you try the following:

- click Start
- click Run
- type: services.msc
- click OK
- right-click on the McAfee Redirector service
- click Stop
- try LimeWire again to see if the issue still occurs

Note: don't forget to Start the service again after testing (or reboot the PC).

I am so happy now, thanks!
