Display Asp MSChart / File Error Could Not Load File Or Assembly 'sstchur.web.survey'?

I've add MSChart to a webpage and I'm also using a Survey page I got from 4GuysFromRolla (http://www.4guysfromrolla.com/articles/061604-1.aspx). Both work on my development machine but when I move them to my hosting site there are issues.

With MSChart page the chart is not displayed although it's included the Page Source code:
src="/ClubInformationTracking/ChartImg.axd?i=chart_3d90c53b0f844807a2491a1d79a636a1_0.png&g=75fecf0f14cf4121b623691d383263aa" alt="" style="height:300px;width:700px;border-width:0px;" />

And when I try to open the Survey page I get this:Parser Error Message: Could not load file or assembly 'sstchur.web.survey' or one of its dependencies. The system cannot find the file specified.

Source Error:
<%@ Register TagPrefix = "sstchur" Namespace = "sstchur.web.survey" Assembly = "sstchur.web.survey" %>
<%@ Page Language = "C#" %>

Assembly Load Trace: The following information can be helpful to determine why the assembly 'sstchur.web.survey' could not be loaded.

WRN: Assembly binding logging is turned OFF.To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.

Note: There is some performance penalty associated with assembly bind failure logging.To turn this feature off, remove the registry value [HKLMSoftwareMicrosoftFusion!EnableLog].

The Hosting site is using Version 4.0 and the dll needed for the survey is in the BIN directory.

When I moved my files to the hosting site I had to change every instance when I referred to a file from:
"~/FileName"
To
"FileName"

I've tried all of the "fixes" I could find for the MSChart that involved changes to the web.config file but because of the error messages associated with the Survey page I'm guessing this is the issue.
