Hi Claire,
I recently upgraded to the latest Microsoft version. If your using Win7 or Win8 you should be able to install this from the Microsoft site (the install should actually do this but ??). Unfortunately this does not work with XP. Let me know what Operating system you are using.
For XP users: I didn't think about this when I did this. I had hoped to get a backward compatible version up on the website this past weekend, but didn't make it. Its on my quick to-do list for this weekend. The downside with this compatible version is that I will probably not continue to update it.
I'm looking into the best thing I can do for all users,
