How do I get back in to my Wordpress Website?

I try http://www.sitename.com/wp-admin

but I cannot get back in to my site admin area.

HELP!

I installed one of your free plug-ins to take my site offline -- now it's permanent.
I do not remember what the plug-in was named.

HELP!!!!!

Help!

After I took my website offline -- using your plug-in -- it is now permanently
off-line. I cannot get in to my Wordpress site.

Help!

What do I do to get past your plug-in.

Of course I use http://www.website.com/wp-admin to
try ad get to my admin panel -- but your plug-in
prevents it.

HELP!
