Hi, I am new in this forum. I am experiencing connection problem with my PL/SQL Developer. It is my first time to connect with 11g and I am getting this error message. I would appreciate hearing a solution from you.

ERROR MESSAGE
=============
ACCESS VIOLATION AT ADDRESS 67614564 IN MODULE 'ORA805.dll'. WRITE OF ADDRESS 00000160.

BTW, the version of my PL/SQL is 7.0.3.1123.

Hope to hear from you.
