There are three reasons for getting LowID, apart from the occasional internet glitch.
1. Firewall. Delete any existing rule for emule.exe and when the firewall asks you again, allow full access to emule.exe (to connect to the internet and to accept connections from the internet).
2. Router. You need to do port forwarding. Go to
http://www.portforward.com select eMule Plus, select your router model, and follow the instructions.
Note that some modems have routers built in.
3. IP address ends in 0. Not xxx.xxx.xxx.xx0 but xxx.xxx.xxx.0 Ask your ISP to give you another IP address.
