If those are the only files that have been marked as changed, they just carry on as normal with your current project.
The .LDB file is just a temporary version of the MS Access file used as part of your RH project. See http://forums.adobe.com/thread/85075 for further details. The othe files are also either temporary or can be deleted. When they are not there, they are recreated. With the .PSS file, this stores some additional information used by the Single Source Layouts. You may find if you delete it that your SSL properties need to be reset, but that's about it.
Thanks, Colum. Unfortunately, deleting the files didn't work. I ended up rebuilding the project from an outdated backup. Fortunately, it was just the master project - all the real content was in the merged projects, and they were safe.
Do you or anyone else have any tips for working with a secured ftp site? I've tried entering the full ftps:// address as the host, but RH9 can't get into the site, so I can't publish directly. I can work around it by copying the generated file, but I'd like to solve the problem.
Sorry that my solution didn't work Marion. At least you have a workaround. I don't use FTP at all so I was more or less fumbling around to see if anyone else had come across the same issue. Of the main contributors to this forum, I don't believe any of them use FTP to publish either. Hopefully someone else will pipe up with a crumb of wisdom.
