[Serusers] CDRTool with SER

I have been working with CDRTool now for a couple of days trying to get it setup. I've finnaly got SER writing to Freeradius, etc. Now, when I try to get in to CDRTool I get past the login screen and am stuck with this error. Fatal error: Cannot instantiate non-existent class: cdrs_ser_radius in /CDRTool/callsearch.phtml on line 58 In my global.inc file I do have this class to my knowledge. I trimmed out all of the options in the array to the bare bones as below and still get the error. Any ideas? The documentation is fairly light for the tool. You would think it would be the opposite since this is supposed to convince you to purchase a license and get hooked. $DATASOURCES=array( "ser_radius" =>array( "name" => "SIP Express Router (Radius Accounting) ", "class" => "CDRS_ser_radius" ), Thanks! -J
