TREX WPC Help!!

I am having a problem with a index picking up the WPC content. I changed the hostname in the url generator, checked the properties, checked the trace logs... Still having problems. The index starts out with an idle status and then after about 1 minute goes to error and displays this error:

/wpccontent/Sites/Help Content/Web Pages/New Page/output.xml

Trex: Preparation failed: index operation

It is finding the content but wont index it. I haven't been able to find a fix for this error. Any suggestions?
