Clipshare ERROR: Failed to find flength file

We have installed clipshare on dedicated linux server and everything is fine except if we try to upload a video clip, we get this error: ERROR: Failed to find flength file We added the recommended solutions to the htacess file and checked that the path is correct in the uploader file. We need someone to fix the problem to make it work as it should. If You can customize clipshare, we will need you for later. Project will go to first service provider who can fix with smallest budget in fastest time.
