Good that you put error message.

I can not access to CBTNuggest at this time, but you can check table structure by right click on the table-->Script table as--> create to --> XXXX and see whether the structure is different.

Example Sales, it should look like.

CREATE TABLE [dbo].[Sales](

[ID] [uniqueidentifier] NULL,

[Num1] [smallint] NULL,

[Num2] [smallint] NULL,

[Num3] [smallint] NULL,

[DateAdd] [datetime2](7) NULL

) ON [PRIMARY]

If you still have the issue, posted your tables structure here.

It may be lot of reason, this may be one of them.

Just my 2 cents.

Thanks
