Entity Data Model System.ArgumentOutOfRangeException

I am using the entity data model to connect to a database. It works fine locally. When I upload my website to the server it throws the following error:

Server Error in '/' Application.
Non-negative number required.
Parameter name: count
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.

Exception Details: System.ArgumentOutOfRangeException: Non-negative number required.
Parameter name: count

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1 

The database on the server definately has the exact same structure and data as it was restored from a .bak file of the original (from which the EDM was generated).

Any help on this will be much appreciated.

For reference sake: this was caused due to my hosting provider changing the port I had to use to connect to SQL server. Not related to the code.
