Hi guys, For the last couple of days I have been trying unsuccessfully to get SpywareBlaster 4.0 to update. The programe seems to download and install perfectly well, but as soon as I click the "Update" button (I use manual update) I just get a blank screen and the program seems to stop working. http://i218.photobucket.com/albums/cc28/gr277/2008-03-02_083128.png The main programe screen Please click to enlarge http://i218.photobucket.com/albums/cc28/gr277/2008-03-02_082139.png The Screen I get when I click "Update" Please click to enlarge http://i218.photobucket.com/albums/cc28/gr277/2008-03-02_082231.png The screen I get when I then try to close the programe Please click to enlarge I must have fully uninstalled and reinstalled more than 10 times, by now, trying to "fix" the problem. My OS is Vista Home Premium. My "protection" is: Vista Firewall - Windows Defender - AVG Antivirus 7.5 - AVG Antispyware 7.5 - WinPatrol (Free) - Vista UAC turned ON. My "maintenance" programs are: CCleaner - Registry Mechanic - AusLogics Defragmenter. I have downloaded using both Firefox 184.108.40.206 (my default browser) and IE7. I have also downloaded from both available servers. Thinking that one or more of my "protection" may be preventing correct installation, I have downloaded/installed after turning off one of my protection programs at a time, but always keeping the Vista Default Firewall and Windows Defender turned on. I have also downloaded/installed after turning off all my protection programs together, but keeping the Vista Firewall and Windows defender on. As you can see, by now I am running out of ideas and this problem is doing my head in . I have been using SpywareBlaster on my XP for a long time successfully. On my Vista, however, I can't get it to work properly. Any assistance will be gratefully received.
