We have recently upgraded to AbleCommerce 9 but before we did that we waited for the AbleCommerce 10 update. With your help, we were able to get the store installed and access Admin. Yesterday, I accidentally

made a change to the connection string for the database and then could not get back to the admin to log in. You were able to provide a link here:
http://help.ablecommerce.com/mergedProj ... ection.htm to edit the database.config file, replace it with the connection string tag, and include my server and original database information. It still does not work; I cannot return to the Login. I have cleared the broswer cache, restarted IIS, rebooted. Is there anything else that I can try?
Server Error in '/cart' Application is the error we receive.
