Can' Install Agent - Can't see the Acronis License Server

Hi,

I installed ABR 10 Virtual Edition on a Demosystem (VMware vSphere 4.1 VM). I installed the licence Server on a VM Acronis with all serials. When I want for physical PCs to install the Acronis Windows Agent they ask about the License Server. I set (in the Win Acronis Agentsetup) the VM Acronis name (or the IP) of this VM where the Licenseserver and all serials are installed) and I can't go furhter! So way cant this remote Server cant see the licenseserver? I can ping the Acronis Vm where the Licenseserver is installed. Firewall is on both Maschines disabled.

Thanks for your help!
