Error in Exporting Final Studio 3 Project to Quicktime

I need to send out my project which I created in Final Studio 3 to Quicktime DV NTSC 48 kHz Anamorphic but I keep getting an error on exporting it. I already tried to create a new timeline but it did not help. I even tried changing the aspect ratio and checked on the hard disk usage but only receive the same problem. Please help me resolve the issue.
