I have used free office for about a week and have been opening and using PDF files without problem. Today i 'registered' as requested only to find that all my pdf files are 'greyed' out and cannot be opened. The programme is useless to me now but why has this only occurred when i agreed to register?...

Hi, I use a Mac and have just downloaded this programme because I thought it could handle existing PDF files. I now see that the free PDF is for windows so can I not open or save PDF files at all please. Michael
