Please Help Cant Log in ! I've read everything

Hello ,
About three days ago i attempted to log into my site and through
wp-admin/ and it just reloads the page with a different link
( http://www.1spg.com/wp-login.php?redirect_to=http%3A%2F%2F1spg.com%2Fwp-admin%2F&reauth=1 ).
I try reading the forums, i have spent hours with my hosting tech support.
I have renamed plugin’s folder and the theme folder.
resetting passwords for users seems to work but cant enter my dashboard.
I’m using WP 3.3.1
php 5.2.17
mysql 5.1.61
Apache version 2.2.22

Please any help could be useful i have about 8 years worth of information that i refuse to loose …
