I was hoping you could help me out with the below error I am receiving when attempting to use the testlink plugin for Hudson.

Here is a screen shot (also attached) of what my hudson project's configuration looks like for invoking the Testlink plugin: http://scrnsht.com/kypwgs

I have a custom field in TestLink with a label of "Automated Test Class" containing the full package name of my test class i.e. com.company.sourcing.gression.splittingTestSuite

Retrieving TestLink details about Test Project, Test Plan and Build.
FATAL: Error creating test project: Failed to parse server's response: The processing instruction target matching "[xX][mM][lL]" is not allowed.
