Disk Director 11 Home Bootable Media boots but does not start Disk Director

Created a Disk Director 11 Home Bootable CD using the Acronis Bootable Media Builder tool available on the Disk Director. Booted the PC with it, got presented the menu and selected Disk Director 11 Home. Then I get the following:

- Full screen with the Disk Director 11 Home logo, then
- On the next screen a square window and under it "Loading the Network Connection Setting ...",

then the screen goes blank and PC starts re-booting. It boots to the menu (mentioned in the first paragraph). I select Disk Director 11 Home again and get the following:

- Full screen with the Disk Director 11 Home logo, then
- On the next screen a square window and under it "Loading the Network Connection Setting ...", then
- On the next screen a square window and under it "Starting Acronis Managed Service",

then the screen goes blank and PC starts re-booting.

My current setup is Disk Director 11 Home build 2343 and Acronis True Image Premium build 6673 on Windows 7 Pro.

I have been using the Acronis products (Acronis True Image and Acronis Disk Director) for years and never had this problem before.

By the way, I created 3 or 4 bootable cd's - using Acronis Bootable Media Builder provided with Disk Director, True Image, and also by downloading the .iso file from Acronis and burning it with Nero, all with the same results. Can't get Disk Director to work. I have no problem getting True Image to work from a bootable cd. I used it many times to reset my system to a previous level.

Any suggestions?

Thanks
