Help with error message in BBrip...please help

I have my Dreamcast hooked up into my router/switch. I also have my desktop hooked into my router/switch. I am using straight through cables.

In order to get my PC to see the DC I had to do the following:
-Load the IP Slave
-Start BBRip on my PC
-Enter IP 192.168.1.103 (which is an IP on my LAN...should be the DC's IP?) I entered this in BBrip
-In Dos I typed arp -s 192.168.1.103 the DC's MAC here
-Then I typed arp -a and I saw that this IP was assigned to my DC's MAC

I then exited and restarted BBrip. My Pc was able to connect. Then I downloaded the track list. However when I go to Download I get an error code 04050100 to the right of the tracks. If I go to reboot bbrip it will not connect again because on the Dreamcasts screen it still lists tracks and does not look like it is ready to reconnect again. What am I doing wrong?? Please help...thanks!
