@seonhyejang, thank you for reporting this issue.

We are going to need a little bit more information to know what is happening when it crashes.

Can you give us more information about what you were doing when it crashed? Also, which version of Blender and RetopoFlow are you using? Are you on Windows, OSX, or Linux? Does this happen when you try using RetopoFlow on the default cube scene?

If you can, please read the debugging docs to see how to gather useful information that we'll need to debug this issue.

Thanks for helping us figure out what is wrong! We'll get you back to retopo'ing as quickly as we can.
