ISO missing after reboot (D-T 3.43/44)

[xdmv]

Operating System: Windows XP Pro SP1
Burning Software: Nero 6.3.0.2
Anti-virus Software: Norton AV 2004 Pro
DAEMON Tools Version: 3.43, 3.44

Hi !
Everything worked fine until v3.41.
After that, v3.43 && v3.44 does not mount an ISO img (the same ISO worked ok on v3.41) after reboot the OS.

I installed the app with admin privilegies (X user).
Then I mounted the img.
Reboot the OS.
Test the game (ISO).
OK.

Close X user session.
Open Y user session (admin privilegies).
Change privilegies for X user to Users (minimum privs).
OK.
Reboot OS.
Open X user session.
Now ISO img is not mounted anymore...

- Do I have to use admin privs to use D-Tools ?

Any help will be appreciated... !
