Checkout fails with Demo Version

For evaluation purposes, I have installed Dreamweaver CS3 and CVS4DW. Both are evaluation versions. When I try to checkout, no files are checked out. Below is the status message displayed:
"You are using DEMO version, limited with some functionality. Please visit http://www.dreamweaver-extensions.net/ if you want to order this software. Thank you.No directories was cloaked."

I am using "Password server" and have left Date and Branch empty. I have entered values for all other input (including 2401 for port).

Note, I have the CVS client installed and I can successfully check from a terminal window.

thanks,
Michael

Please note, this is on a Macintosh running Tiger.

Hi, indeed checkout is restricted in demo version, only commit, update will work. This is because we didn't found an another way to offer demo.
