SharePoint 2010 Server Error in '/' Application

'table' argument cannot be null. Parameter name: table 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.
---------------------------------------------------
A couple of days ago users began receiving the above error (more details below) when going to the SharePoint 'home' or landing page (all other pages/sites and even this sites libraries and lists do not throw this error). Also administrators and myself do not get this error so initially thought this may be something to do with security or permissions. I have checked this to the best of my ability but do not see anything out of place. I have scoured the net and come up empty handed...

Thanks! That did it.....not sure why this web part broke all of a sudden as I have not changed it since it was installed many months ago but will contact the company as you suggest.
