Serialization errors..

Hello!

We use JSON to serialize things to disk. But now we have started to get exceptions when deserializing the data.

The exception is...weird:

 System.MissingMethodException: Method not found: 'Default constructor not found...ctor() of System.ComponentModel.Int32Converter'.
   at System.Activator.CreateInstance (System.Type type, Boolean nonPublic) [0x00000] in <filename unknown>:0

So...all of a sudden, JSON can not convert ints..?

Thx in advance! (btw.. not a problem in the editor, just on the iPhone)

Edit: Our "CurrencyManager" is just a class with 2 int:s in it.
