I have been trying to list all afternoon and evening. The program gets hung up and closes. This all seems to have happened after I updated. any clues on how to solve this problem?

One error message I got was:
Internet error: 200 Type Set to l. 200 Port Command Successful. 425 can't build data connection: operation timed out.

I only got this error message once. Other times it just hung up and I had to ctl/alt/delete to close the program.

I have rebooted and still won't list. Just gets to the FTP upload and freezes.
