Plugins vanished

I moved my blog from http://barebonesgraphics.110mb.com to http://bbgraphics.fh50.com/ because the latter is more reliable. There have been a few problems with themes and such, but the main problem is that the Manage Plugins page says I have no plugins installed.

I have All in One SEO Pack and WP-Cumulus in my plugins folder (wordpress/wp-content/plugins).

Any help?
