I am having an issue getting my command line data loader to function.  I am using date loader 23.0

I have encrypted the password and security token as outlined in the cheatsheet for 9.0. 

I have verified that I can log onto data loader using the userid, password and security token, so I know the user is not locked out.

Here is my error message:

java.lang.RuntimeException: Invalid username, password, security token; or user locked out.
 at com.salesforce.dataloader.process.ProcessRunner.run(ProcessRunner.java:134)
 at com.salesforce.dataloader.process.ProcessRunner.run(ProcessRunner.java:74)
 at com.salesforce.dataloader.process.ProcessRunner.main(ProcessRunner.java:226)
Caused by: [LoginFault [ApiFault  exceptionCode='INVALID_LOGIN'
 exceptionMessage='Invalid username, password, security token; or user locked out.'
]]

Here is the password portion of my code:

<entry key="sfdc.password" value="41683bf7a6a116b7d92ce4e857e7b510"/>
                <entry key="process.encryptionKeyFile" value="C:\Program Files (x86)\salesforce.com\Apex Data Loader 23.0\conf\Key.txt" />

Any ideas?
