Re: Missing configure.php (Pls. help me!!!)
Have you tried renaming the file dist-configure.php in includes/ and the same file in admin/includes and change the path and SSL settings if need be and re-upload just those files?
I may be wrong, but I do not think that the configure files do anything other than paths, SSL, and some minor database paths and cache should you should (hopefully) not have to re-install. Give it a shot and the worst that can happen is that you woudl have to copy your current files out of the way, re-install and copy the files back (but again you should not have to).
Good luck and may the force be with you
