Oracle client being used is not supported.
Update your Oracle client to a version that is supported by the version of Toad for Oracle you are using. You can find out what Oracle client version is supported by looking at the System Requirements section of the ToadGettingStartedGuide.pdf file. It can be found, by default, in the C:\Program Files\Quest Software\Toad for Oracle x.x\docs directory.
