IDE Crash when converting C# to Oxygene

I get the following when converting any C# file to Oxygene

Value cannot be null.
Parameter name: collection
at System.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument)
at System.Collections.Generic.List1..ctor(IEnumerable1 collection)
at RemObjects.Fire.BaseLibrary.FBLFileBuffer.save(Boolean force)
at RemObjects.Fire.ProjectSystem.TextFile.<>c__DisplayClass32.b__0(String code)
at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)
at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)
