Outlook 2k3 and the latest security patchs for Windows XP


Just recently i patched my computer to the most latest MS security patches for Windows XP. In this patching I now can not open outlook 2k3 because it believes there is malicious coding running in the background. So I uninstalled kleopatra and now it opens up without issue but I can no longer run Kleopatra. Is there away to get the latest Kleopatra to work in XP now that I installed these patches?
