Master Master Replikation broken Slave_IO_Running: No (no replies)

Hi,

I've got a new project, an existing MySQL-Cluster with Master-Master replication. This replication is broken and I need some help to fix this. It' s mysql-server-5.0 on a Debian Lenny

I have tried to change the position on mysql01:
stop slave;
cHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.1533', MASTER_LOG_POS=92882430;
start slave;

I have tried to change the bin file on mysql01:
stop slave;
CHANGE MASTER TO MASTER_LOG_FILE=mysql-bin.001530, MASTER_LOG_POS=4;
start slave;


But this has no effect. Please help...
