"May relate to execution of code runtime compiled inside
of the SoapHttpClientProtokol constructor which calls during runtime the
codedom to generate an assembly to load it in the memory.

Unfortunetly it seems to me that this in-memory generated assembly that is
being used to access the Web Service is an unsigned assembly that therefore
cannot be given any rights under a "run-signed-code-only" security policy."

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.

I tried clicking on continue the error dialog box comes back, better yet it pretty much blinks for a second and reappears. There is also another dialog box stating :
Please wait while windows configures Document Viewer. This box stays idle and cannot be activated whatsoever.
All of this happened after installing a new AntiVirus software.

Any suggestions??
