System.Net.HttpListener

Hi.
Can anyone help please?
Am suddenly getting an error
“Can’t reach this page
Make sure the web address c://http:localhost:53561 is correct”
Then getting an unhandled exception error message which says

Cannot access a disposed object
Object name : 'System.Net.Http.Listener'

The details for the error are : 
See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (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 computer
rather than be handled by this dialog box.

Have tried uninstalling and reinstalling Manager but still get same issue.
Any help would be really appreciated as I cannot access my accounts at this point
Thanks

Can you try to install server edition? I suspect server edition will give you different error which will help trace down why desktop edition doesn’t work.
