Can't access Restored MYQSL Wordpress files via FTP

I deleted a bunch of posts in error in a Wordpress blog, and successfully restored them using the restore function for the mysql in Dreamhost .

Now when I go to update the software in Wordpress get a request for my FTP details. Whatever I put in there, will not let me do the update.

When I use my FTP client I can see the files but when I try to delete one I get messages like 550 front.gif: Permission denied

I have another blog with the same user and I can delete files there.

I’m wondering what the difference is. In both cases the files are set to: drwxr-xr-x

Turns out there was a problem with my username - which I’d changed since the restore, Dreamhost support fixed it. I’m not sure where or how! Thanks!
