Can't start J2EE engine after failed EP upgerade.

Hi,

I have upgraded my Web AS 6.40 to sp 13, but when I was installing the EP upgrade something went wrong and I had to cancle the installation. Now the J2EE engine won't start anymore. I can't se any error messages, it just keeps trying.

What can I do? I have tryed to run the installation of Web AS sp 13 again but have the same problem......

Do I have to start the installation from scratch, and loose all of my installed components?

Best Regards,

Morten
