Hi all,

I'm trying to replace a text from a word 2010 file (.docx) and i've some issues when running the game, I'm using DOCX managed library, could be found here.

Here is the code:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using Novacode;
4. using System.IO;
5.  
6. public class doc : MonoBehaviour
7. {
8.     void Start()
9.     {
10.         stringReplace (Application.persistentDataPath + "/OSMLAB Cervical.docx", "NICKNAME", "myname");
11.     }
12.  
13.     void stringReplace(string file, string textToReplace, string text)
14.     {
15.         DocX document = DocX.Load (file);
16.         document.ReplaceText (textToReplace, text);
17.         document.Save ();
18.         document.Dispose ();
19.     }
20. }

the problem is when play start, it throws this exception:

I've tried in Visual C# with exact code and it works perfect.
