Does emulator run with your device when you use run App Inventor at home?
If it works there it is probable the school is blocking port 8004?

What Operating System version are you running the emulator on?

Simply use App Inventor Companion on your (Android) device or run your APK? You can potentially screen-cast your Android device to the PC.

The reasons for any emulator failing are far and wide unfortunately. One I found was an extension working fine on Android but the emulator would not work with it. At the time I used a 3rd party emulator, BlueStacks, as a work-around, which worked very well.
