Abode Captivate- Captivate encountered an error when post-processing the converted presentations

Hey guys!
I am using Adobe Captivate most of the time specially for creating presentations. But this morning I encounter a problem when converting swf to avi format. What I wrong? Why this error appears? Is it error to my file that I want to convert? Thanks.

OK
