Deleting AJAX Control Toolkit?

I am working with Visual Studio 2010 to develop ASP.NET pages with .NET 4.0 framework.

Background:

I was working on my website and I discovered a new functionality called NuGet which allows one to download packages to enhance the functionality of project. I downloaded several packages related to statistics and geographic information systems. But when I FTP my website to the server it broke my website. The original error message had to do with "Could not find or load assembly AjaxControlToolkit or one of its dependencies". Fortunately a person at our IT department went into my code on the server and commented out several lines related to the AJAX Toolkit. This fixed my website on the web.Unfortunately I get error messages when I attempt to FTP new pages to my site.

My attempt to fix issue:

1. On my local machine where I develop my pages I go through all my pages and comment out anything that has to do with the AJAX Control Toolkit or the AJAX tools that Microsoft provides. For some bizarre reason my website decided it did not like AJAX anymore. So I get rid of all of it.
2. In the Packages folder I delete out all the stuff I downloaded from NuGet such as my GIS and statistics stuff. I also delete out the AJAX stuff.
3. I delete the Packages.config file
4. Under the Build menu I choose Rebuild Solution and Visual Studio returns 'Succeeded'. I also choose Rebuild Web Site and it also Succeeds. I run my web site locally and it seems to work fine.
5. I then use the Website menu and choose Copy Web Site. I log into my FTP and on the left hand side I choose a file to copy from the Source to the Remote. I receive the error message: "There were errors during copy web. Please view log for details". I then click the View Log button and the message is:

"Copy from 'C:\Documents and Settings\kulpandm\My Documents\Visual Studio 2010\Projects\LCEMS' to 'ftp://MyFTP started at 5/17/2013 9:08:46 AM.

Copy file LCEMSDataPortal.aspx from source to remote Web site.

Request Assistance

I google this message and come up empty handed.

I can't FTP anything to my server. What do I do to fix this?

I have a strong suspicion the AJAX Control Toolkit is part of the problem. That is why I am posting this issue here. Would I be correct?

In your reply to my issue do not be afraid to be too specific in your answer. I am an amateur web developer so I need as much direction as possible.

thank you for your kind assistance,
