can i force my player to keep the same IP address? the first six digits are always the same but the others always change.

i had to (downgrade) from 2.00 beta 11 to 1.3 to get my player to add songs. Now that 1.3 is running on the player, the IP address is listed as none. Emplode cannot locate my player on the ethernet port now either, just COM1. That serial transfer is sloooow.
