You need to shutdown mysql, delete the master.info and
relay-log.info files and then start mysql again.
The reason for this is because if the info files are
present then mysql uses them as is and only recreates them
from my.ini or my.cnf if absent.
This should get your replication going again.
Tried that, but no luck, they get recreated, but they still have 0 bytes in
them. This is really driving me crazy because although it's come up before

Based on your explain, I'd guess that you don't have any indexes. Probably,
you need (at least) an index on the join column on the second table, as,
otherwise, MySQL will read the second table once for each row of the first

This probably doesn't have anything to do with the fact
