I've used Elements 4 but have had some problems with it. I know most of the problems will be down but recently I've found that the whole system locks up and I have to resort to the alt/con/del to get out of it. I've run through a check on the software and the report suggests that I reload the software. After this it seems to work for a while. I'm thinking about version 6 but do I have to un-install version 4 first? Of course, making sure I've got copies of my files. I'm sorry if this is something dealt with before but would be grateful for help.
