Mouse does not work with Acronis Media Builder bootable CD

I tried my bootable CD created with Acronis Media Builder (ATIH 2011), but the mouse is not working : right or left click does not activate the buttons :
- I could not switch off the computer by clicking on the "Switch Off",
I can move and select with the mouse but nothing occurs when clicking.
If somebody as an answer (the CD was created with "Complete Acronis" not "Safe").
