Help Needed WordPress Blog

My Web Host provider blocked my account for a few days. Now, I can’t get my blog working. The Web site is working fine, but he blog is in a subdirectory (public_html) and is not working. My account was blocked because a plugin I installed in the blog was making hundreds of backup files in the blog directory. I’ve backed up the blog from an installation made the day before all the trouble, but the blog still doesn't—I just get a blank page (there is no error message). The blog should work, I've backup this way before; all the needed files seem to be present, but I can't see the front end of the blog. So, I have three things that I need: 1. Get the blog working again. 2. Remove the new plugin (WP backup) so it doesn’t keep making so many backups. 3. Get the old backup system working (a plugin that uses Amazon S3, Automatic WordPress Backup [Volcanic]). Thanks,
