If anyone is having problems loading the android emulator...

Then install this Intel Hardware Accelerated Execution Manager program.

I started the emulator, but it did take a long time, but in the end the program appeared and android Lollipop booted up.

The funny thing was that I had already installed"Intel x86 Emulator Accelerator (HAXM installer)" in the SDK manager.
