Nero Vision 4 Start-Up Problem



I use Nero Vision 4 (Nero 7 Premium Re-Loaded) as my DVD and CD burning programme. My OS is Windows XP Home.
However, it’s kind of hit-n-miss whether the programme will start-up or not. Very often (too often) as far as I get is the Nero Vision 4 Window (after clicking Nero StartSmart) and then it freezes. I’ve tried uninstalling and re-installing more than once but to no avail. Anyone any idea’s as to what could be wrong ?
