Hi Keli,
Welcome to the forums! 
A problem that many people have reported with Expression Trial behaving strangely is that they have not rebooted their computer after the download and before using it. If you haven't done that please try doing a full cold start reboot and see if any of that clears it up for you.
If that doesn't help or you have already done it..please let us know and maybe there is something else we can try.
