I2C protocol and Acelerometer MPU-6050

Hi, I have a question, I have to use two devices with the I2C protocol, the RTC DS1307 and the GY-521(MPU-6050). I change the acelerometer's adress connecting the ADO pin to 5V, I can read the RTC without problem, but the acelerometer give constant values, when I disconect the ADO pin(without the RTC) the acelerometer go well, ¿How can I fix this problem?. The GY-512 also have XDA, XCL and INT pins. Please, help me.

Hi, I fix the problem, I only change the value LOW to HIGH in the MPU-6050 library, thanks.
