Playback speed is not working

 

I support technician at the Court, and we are in trouble on the button to accelerate or slow down the audio. When I change the speed, the audio continues normally, ie, does not change anything.

We performed the following procedures:

 

- Removed the FTR using Revo Uninstaller which removed to the records;

- Removed the FTR manually following the tutorial forum;

- We use version 5.6.0.0 and even upgrading to 5.6.2.0 the problem continues.

- The files played in the extension. TM does not work to change the speed, but the MP3 files usually work;

- The operating system is Windows 7 Professional 64-bit.

 

Has anyone had this problem and solved?

Thank you.
