Okay, I assume you downloaded the program from within the manual, at cuteftp.com? I am walking through the process with you, and went to the site, then clicked: Downloads > Evaluation Software. I chose this link to download CuteFTP Home:
http://www.cuteftp.com/downloads/cuteftp.aspx
I chose the default one (English/Windows), put in my email address, and clicked submit. I clicked the Download Now link on that next page.
Is that what you did?
Once I installed it and opened it, I got a Welcome message. I chose "continue" (instead of Enter Serial Number). Then it went straight to the connection wizard.
Try to cancel out of "maintenance" (not sure what that is you're seeing?) and go to File > Connect > Connection Wizard.
If you have to, uninstall the one you downloaded and start over. Maybe you got the wrong one??
