Bitdefender 2009 - Blank Screens


When I install BD Antivirus 2009, on my desktop the screens are fully blanked out and only the outer line I could see. I tried uninstalling and installing, noting worked. I tried cleaning the registry too. I have Windows XP, Sp2 installed and IE 8 is installed. I dont know, if there is any dependancy to install this. It is working fine in my laptop. Can anybody suggest or fix this issue. Appriciate your help.
