Q:
After upgrading EMP Monitor on my computer, no projectors appear on the screen when I launch EMP Monitor. What’s wrong?
A:
When a projector is registered, the settings are saved to a file called EMP Monitor.dat. When you upgrade to a newer version of EMP Monitor, this file is replaced with a new version. You need to register the projectors again for them to appear.

To avoid having to re-register the projectors, copy the EMP Monitor.dat file (located in the EMP Monitor folder under Program Files) to another location on your hard drive before upgrading EMP Monitor. After upgrading EMP Monitor, copy the saved file back to its original location. When you open EMP Monitor, all the registered projectors will appear.
