while i can't confirm that this works, i was told to delete fire.dll and fire.u from system folder, then you can log in using IG walker 1.46. hasn't worked for me so far but just what i was told, and im still working on it.
change your set.ini to:
[DEFAULT]
CountryList=theabyss;
DefaultCountry=0
DefaultServer=2
DefaultCharacter=0
DefaultAccount=rick123
DefaultPassWord=
[theabyss]
LoginServerIP=85.112.114.77
LoginServerPort=2593
ProtocolVersion=659
ServerList=[1]3x;[2]300x;[3]7x;
and run it the usual way should work
