Problem Creating RIS Server Boot Media with Acronis True Image Echo Enterprise Server

I have a problem with creating Bootable Media for a RIS Server on my Server
Win2003 SP2 installed
WDS configured
Acronits True Image Echo Enteprise Server installed

The following error appears:

E00040011: Erstellung des Mediums fehlgeschlagen.

Kann erforderliche Komponenten nicht laden. Installieren Sie Acronis Testprogramm erneut. (0x40011) Tag = 0x3ADB35B62A9DCD9A Angegebene Datei existiert nicht. (0x40011) Tag = 0xCD91BB81F2747200

(Strange thing is, that its about a "Test-Programm" but i have installed the full version of the server)

Anybody can help me?
