connection timed out on ftp quickconnect

I am trying to install WP using FileZilla. I enter my credentials and click quickconnect, and I get the following:

Status: Connecting to 97.74.42.79:21...
Status: Connection established, waiting for welcome message...
Error: Connection timed out
Error: Could not connect to server

I confirmed these were the same UN/PW I set up when creating my account on WPMU hosting. Thanks!
