IdeaBlade.EntityModel.EntityManagerSaveException

   Hi, I get the following exception when trying to save an entity:

Exception msg: The remote server returned an error: NotFound.

Stack:
   at IdeaBlade.EntityModel.EntityManager.HandleEntityServerException(Exception ex, Boolean tryToHandle, PersistenceOperation operation, Boolean throwOnError)
   at IdeaBlade.EntityModel.EntityManager.HandleSaveResultException(SaveWorkState saveWorkState, Boolean isAsyncOp)

System.ServiceModel.CommunicationException

I create the entity in the same way that I create entities throughout my entire project.
For example:
 var newNode = EM.Instance.CreateEntity<Node>();
 ... Then add a bunch of properties to the node, eg: Name, Size, etc.
 Then I add the entity to the Entity Manager (EM) via: EM.Instance.AddEntity(newNode);

 Lastly I save the entity asynchronously: EM.Instance.SaveChangesAsync();

Now for the bit of wackness that I'm experiencing:
- When saving other entities, Ideablade works beautifully.
- When saving a "Node" with a size above 2MB the exception gets thrown.
- When saving a "Node" with a size below 2MB, Ideablade works beautifully.
+ What's really wack, would be that this just started happening, previously I could upload "Nodes" with size above 10MBs.

I would GREATLY appreciate it to just be informed what this exception is, as I cannot pin it down by debugging.
(I'm aware of the fact that chances are 99.9%, that I'm just being a nab, and I'm okay with that, I'm kind of just hoping to be pointed in a direction to start solving this problem.)

Thanks in advance for any help.
