Nexus Manager 8.4.4 Will not launch under Leopard(10.5.8)

[Prepress_Parasite]

I am having trouble getting Nexus Manager to run on a new Imac. It is giving an error of "The application Nexus Manager could not be launched because of a shared library error; <NexusManager>(NexusManager><ArtDbaseAccess><>
Any help would be appreciated.
