Ive ben having this re-occuring problem with the different versions of adobe Reader where it wouldnt opening a pdf. file. it won't open which then causes me to then re-start the machine and works after ive done that. But this is constant and have to keep restarting my pc over and over. i even have trouble with printing documents as well where it wouldnt come on screen or wouldnt come up at all! is there any way of solving this is issue as this has become quite fustrating! can anyone help me?
