I have had LimeWire running for a few days as an Ultrapeer. No problems with the connection through Opera whatsoever, but somewhere I got "kicked off" the Gnutella network while being an Ultrapeer. How does that happen?

1. Windows XP Pro SP2
2. Windows
3. 1536 MB/1.5 GB
4. 4 disks of 200+ GB total. Available, about 120GB
5. Cable modem
6. Motorola SB5101 modem, HP NC3163 Fast Ethernet 10/100 NIC
7. Home
8. LW 4.12.6, Java 1.5.0_09
9. Romerike Multimedia (Local Norwegian ISP)
10. It worked
11. No
12. New problem, but not quite experienced user
13. It starts with a brick wall, which disappears after a few seconds
