Error on Wishlist improvement

[jonsecu]

Hi... I am developing some modifications using the blockwishlist module as a base. I followed this steps:

 

1. Install prestashop 1.6.0.8 cleanly. 
2. Started a new project on php with the existing sources on modules/blockwishlist.
3. I developed my modifications... they work well. I tested them and uninstalled the module, then installed the module again and tested them again. So far so good... nothing is broken and everything works smoothly, both the basic funtions and my mods. 
4. I created a new prestashop installation. Eliminated the original blockwishlist module folder and copied mine instead. 
5. Here comes the problem... when I try to install my module, the same one that I was able to install and uninstall before, now the installer says that there are 2 errors:
   1. The module cant be autoupdated.
   2. The module wishlist maybe corrupt. 

I believe this has to do with the fact that it is a native prestashop module. How can I solve this problem? I just want to be able to install my standalone modified module on a production store. 

 

Thank you very much.
