I had attempted an upgrade to 1.5.1 that didn't go well. After restoring the database I re-uploaded my previous version (1.3.9h) and now only receive a black page when going to my website (www.diyledexpress.com) If I put the site into Maintenance Mode the front page updates and shows the Maintenance image. I can't figure out what I'm missing.

I noticed I am missing some payment modules. All I see is the modules related to Authorize.net. Can anyone help? I'm supposed to start a very large sale tomorrow and am in a world of trouble!

Thanks!
Todd
