cubase 6 import audio

Hi there,

I have recorded some e-learning courses for a customer. I have cut the audio into specifc files and saved them as wav files.

The customer wants changes to two of the files and so I have imported the two saved wav files back into the project.

However the end of the file is being cut off almost as if I had set the out marker in the wrong place. Its cutting about half of the last word of the file.

I have checked the files in media player and they run full length and also import into another audio prog no problem

Please can you advise???
