photoshop elements 3.0

i have macbook 2009 reloaded new os. programs deleted. have reload photoshop elements 3.0 sucessfully.  when trying launch error message;  invalid personal initialiazation not found.  product registered.  can this?

pse 3 stopped being compatible os x around 10.4 (i believe run then, no longer reinstalled.) if running mavericks need upgrade version of pse. pse 12 current version.
