I keep on getting a reported fault that a PSI key is not working correctly, or is missing, and that I must download a 'fix' from the Protexis INC website. Whatever I do, I cannot sort out the problem. I am also having problems with Office Word. Whenever I try to Save a document, the system crashes/hangs, and goes into auto recover mode eventually, or sometimes I need to restart and do an Office Enterprise repair. Are these problems perhaps related?
