SKYPE RECORDING ERROR

Hi

I have had a couple of unavailable skype recordings and i tried to save them by using "Users\AppData\Local\Microsoft\Communicator\Recording Manager\Temporary Recording Files" this steps (by creating new record and delete new one and paste old ones). It worked for all of recordings except one. That one seem to be completed but when i click it, its only 33 second and i know that its about 1.5 hour because i see this length on recording manager. Also when i click to AV file on recording, i can hear all voices on recording but when i complete the video it does not appear that way. Can you help me please its very emergency situation.

Thank you
