Following installing the LiveAnnouncement plugin I now face a problematic scenario. My admin page is broken and I cannot seem to remove the plug-in to fix it.

If I remove the plugin from the appdata/InstalledPlugins.txt file I get the following error:


Method not found: 'Boolean Nop.Core.Domain.Common.CommonSettings.get_HideAdvertisementsOnAdminArea()'.
  Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

and if I remove the live announcements folder from the plugins folder I get a


No parameterless constructor defined for this object.

I can see that the plug-in has added an announcements table to my database which obviously has created some sort of dependency on this plug-in but cannot understand what I can do to remove it completely and return to my happy working state.

Any help would be greatly appreciated.
