MPU6050 - original i2cdevlib works, but freeimu don't

It was something strange happened to my MPU6050 sensor or maybe to me Arduino UNO R2 board.

When I want to read yaw pitch roll angles using i2cdevlib and open example sketch

MPU6050_DMP - everything works

MÍInitializing I2C devices...
Testing device connections...
MPU6050 connection successful

Send any character to begin DMP programming and demo:

when I use FreeIMU example sketch

MPU6000_DMP i get error

Initializing MPU device...
Testing device connections...
MPU60X0 connection failed

Send any character to begin DMP programming and demo:

DMP Initialization failed (code 1)

EDIT:

ok, I reload freeimu library and forgot to configure it :)
