Access Violation Error 00190000 on Updating Ad Aware Antivirus

Hi! Friends,
I am posting here my experience in updating my Antivirus software. I downloaded and installed Ad-Aware last week, when I wanted to update its definitions and I clicked on update,an error message box appeared.

Access violation at address 00190000. Write of address 00190000.
Above is the screen shot of the error. When I read the error, I am worried if this will go on and that I cannot update the virus definitions.This anti virus software is useless, since it cannot detect anymore new virus, I tried to remove the software and re install it again. when I tried to update again, it failed to update for the same reason above.
Please help me with this problem.
Thanks.
