The program seems to install, but then when I restart my computer, it freezes. I forced the computer to shut down and then restarted it. After restarting the computer, I opened the program and the welcome screen appears. When I try to begin a new project, the box opens to name the project, but then it freezes. I have uninstalled and reinstalled the program and restarted the program many times, but the same thing continues to happen. I also downloaded and installed the 9.0.1 update, but I still cannot get the program to operate. I'm using vista and have 4 gigs of RAM.
