MPU6050 Code Message

I am having an issue when I try to compile a sketch I found on the internet. The origonator says that the sketch works but I keep getting a error message that says "Class Mpu6050 has no member named initalize". What does this mean?

Either there is an error in the code or you do not have the proper library installed.

Please read and follow the instructions in the “How to use this forum” post.

Mine MPU6050 is working fine with this Library File.
