Sounds like you don't have an entry named LoY in your launcher table in the database.
if you do a search the syntax for the table is around here somewhere. I think it just needs a name and a number of dynamic zones.
EDIT: I found the syntax, boy I am a swell fellow
insert into launcher (name,dynamics) values ('LoY',6);
where the number 6 would be your total number of dynamic zones.
