update May 18: consider it closed - read last msg !

Dashboard -> 'Manage Main Menu': whenever I try to 'Edit' or '+Add Item' I get below error. Although, I'm able to 'Delete' a menu Item!

I tried to resolve by:
- deleting the 3  Migration records in .sdf
- deleting all szmyd. data records in .sdf 
- then deleted  Module 'Szmyd.Orchard.Modules.Menu' and reloded the 1.4.1 version from the 'Gallery' - NO change.
Whether I'm in Orchard 1.4 or 1.4.1 doesn't make any difference either!

PS: the Migration and the data records got created correctly again! But I cannot '+add items'!
BUT: then I copied the  'App_Data' folder from my saved project and all is ok for the 'end-user' .... but still no editing of the Menu i.e. same error see below!

 Any help is appreciated - something must have changed - I don't have any clue!
Thanks for your time

The info above has been taken using WebMatrix. Now I tested the same in VS2010 and get some more info but , I guess, it's the same error.

in 'AdvancedMenuItemPartDriver.cs' I get

error: 'Object reference not set to an instance of an object.' (the bolded  code, starting line 53, is highlighted at time of error)

part.AvailableItems = new SelectList(new[] { new SelectListItem { Text = T("(None)").Text, Value = default(int).ToString(CultureInfo.InvariantCulture) } }
                .Concat(routables.OrderBy(x => x.ContentItem.ContentType).ThenBy(x => x.Id).Select(x => new SelectListItem
                    Value = x.Id.ToString(CultureInfo.InvariantCulture),
                    Text = string.Format("{1}:\t{0}", x.As<TitlePart>().Title, x.ContentItem.TypeDefinition.DisplayName),
                    Selected = x.Id == part.RelatedItemId
                })), "Value", "Text", part.RelatedItemId.ToString(CultureInfo.InvariantCulture));

... what have I done wrong

thanks for your time, ed

my apologies in case you spent time reading it!

after some long nights I realise that one of my own Module is obviously interfering with with the 'Advanced Menu'! Removing my Module brings all back to order!

well, still a lot to learn , ed
