A year ago I wrote about runtime error. I could not get it to work with your advice so I just remove the program and reinstall it. I am interested in purchasing 11 but I have seen written that 10 also had this problem. How can I know that this is not also a problem with 11? I know it can be returned but the problem happened with 9 after the time to do this was over. I am looking at other programs but know this one and except for this one problem I really like it.
