I had to talk to my DBA to use the tool and connect the tool to the dababase using the SYS login. He dropped the SYS.PLSQLDEV_AUTHORIZATION table.
That did it. This can close.
Sorry but this link did not help. I'm not using the beta version and I don't see any pl/sql dev tables on the database. I'm not a dba and my dba does not know this tool. How do I connect to the database as a system? Is this something that my dba knows?
Thanks.
