I uninstalled Microsoft Office 2003 (which came with my XP computer), but then Microsoft Word Processor stopped working, and when I try to load it, a box pops up saying, "This application has failed to start because LTKRN13n.dll was not found. Re-installing the application may fix this problem." How do I reinstall Word? >_< (Are there any options besides trying to buy a CD to re-install the program?)
