Multisite installation gone wrong

To PC: Thank you for your help. Here is the main site (still being tested). It says here on this form NOT to give log-in info, so if you could give me the right form to use, I’ll send you more info. I have created two additional sites, which don’t work: and I would like to have you look at this if you can. I’m almost certain it is an htaccess problem, because I changed it to subdomain install = false (which is what I want) but I can’t figure out how to regenerate the htaccess file. Thanks in advance for your help, & let me know how to contact you. Finally, what do you need for FTP? I never use it, I just log into C-Panel at Bluehost and edit my files there. ~Matt
