The system NAND flash for the emulator has run out of space. Your host system D: is not the issue, but for some reason the system.img file that represents a NAND flash for the emulator is full. You can try creating a new emulator, or doing a factory default reset in the emulator to clean it up. To do this, either issue a Factory Data Reset inside Android under Settings -> Privacy, or start the emulator from the command-line:
android list avd
emulator -avd My_Avd_Name -wipe-data
The first command list all Android Virtual Devices. You need the name for the second command. The emulator should not already be running. A third option would be to delete the disk images located under your Windows profile. Under your profiles, it's .android/avd/My_Avd_Name.avd You should only need to delete userdata-qemu.img and maybe cache.img. You can try deleting other image files if necessarily, but note, sdcard.img won't be re-created automatically. You need to run mksdcard from the command-line.
