Can't Add Virtaul Device

[Viatool]

Hello,
I have a Problem with Demon Tools Lite "Free License" on my WinXP Home Edition..
It's Installed and it Start up "normaly".

The Problem:
After "Add Image" i can not Play the Image. The Play Button is not available.
I think it is because of there is no "DT Virtual Device".


What i did:
-Add "Virtaul Device".


The Problem:
-it is not happening. It says "Adding Virtual Device"
- "Reboot is required for Changes to take effect."


Nothing happens. Still the same Problem after Booting.

Please specify your DAEMON Tools version. Do you use any security software?
