Problems and Errors , Arduino Micro-Atmega32U4.


I have problems using the new Arduino micro With atmega32u4.

One need 5v connected to RESET to detect forever.

The other green LED lights ON but nothing more.

At the same time a mega Arduino and Arduino Nano I had with nfr24l01 as sender and receiver both do not work from one day to another.

No serious project possible.

Experiences? Some tutorial to load bootloader from one integrated chip or other Arduino micro? Arduino micro must have reset button to run correctly?
