Oracle Database Discussions

Hi all, this is my first experience with Oracle databases and my first post here so please bare with me...

I successfully installed Oracle Xe 11.2 and I am using a third-party script to setup my database tables, etc. unfortunately though I am repeatedly receiving error ORA-28575. I have searched for likely causes to this problem and it seems it is mostly caused by a bad configuration in the listener.ora and tsnames files.

Can anyone spot any problems with the configs below??
