Support said it was my video card drivers or sound card drivers that were at fault for their Registration screen appearing.
You only here this excuse when the software is known to be buggy, its the most lame excuse ever.
So I sent my DXdialogue.txt (whatever) and finally got told that Cyberlink don't support WINDOWS-SEVEN.
PROBLEM FIXED:
Have uninstalled this stupid software and am also uninstalling Cyberlink Instant Burn off another machine (XP) cause it made the Samsung bluray drive go into an endless-loop which required me to turn the PSU switch (on the machine) off to kill it.
