Make sure you are backing up your databases
Thanks for your reply. Here's the followup: Reinstalling didn't work. Contacted FM support and finally figured out it was what I had suspected - the application was open, but was somehow shoved completely off-screen. With Windows 7, the solution is to press and hold Alt + Spacebar, then click the icon on the taskbar. This brings up the window control menu (Restore, Minimize, Maximize etc.). Then you can click Maximize or whatever you want, and everything is normal again.
