I did the following steps, but didn't have the DSLocalizer working, am I missing somthing?

The steps:

1- installed the module.

2- added the following to Skin.xml:

"<Object>
  <Token>[DSLOCALESELECTOR]</Token>  
 </Object>"

3- created a new page

4- added DSTabLocalizator and DSLocaleSelectorPA modules to the created page

5- Tried to install Hack but got the following error:

6- enabled "Use Tab Localization" and "Use Module Localization" in the general options.

7- I changed the "Tab Name" of the home tab with different name per language.

8- but i got nothing changed when switching between the languages....."Why"?

Thanks in advance for your support.

From your error I can see that the error is ocurring at:

DotNetNuke.Modules.Repository.MakeThumbnail.Page_Load

So the problem is on the module named repository and not in the DSLocalizator

Are you using localized replacements? if yes, be sure you are not replacing needed content for this module
