I've been working with CR XI for about a year and still don't understand the more technical aspects of it. 

I work on a network system, but CR XI is installed only on my machine.  I installed CR Server on my computer too, but have never set it up or used it.  I tried to uninstall it a few months ago, but keep getting an error msg and it won't let me.  I have given up on that.  At the same time I tried to uninstall the Server, I installed the upgrade to XI R2. 

For reasons that I won't get into, XI R2 was uninstalled and the original CR XI was reinstalled.  Since then, I get an error msg when I try to access the Repository.  Here is the error msg that I get...

"The system dawn.***.lan can be contacted, but there is no Central Management Server running at port 6400"

What happened to it, and how do I get it back??
