there could be an even simpler reason, your hard drive could be nearly full. even if you are using fab to burn straight to disc it still needs to copy film image temporarily to your computor which in some cases can require up to 8 gigabytes of space. if you click on my computor it should tell you how much space is available. fab also tends to save previous films in your programs folder which can take up massives amounts of hard drive if you forget to remove them. to check click "MY COMPUTOR" then "PROGRAMS" look for large folders of at least 3 gigabytes, remember not all films are called by their title, and delete as necessary. if you are not sure if it is a film folder then click it open and you should see 2 folders inside, AUDIO_TS and VIDEO_TS.
