Unhappy [Q] Help!! Link2SD package invalid when trying to make Link

Hello guys
I have Sony Xperia L - Jellybean 4.2.2 - 15.3.A.1.17 - Rooted Stock ROM - Locked Bootloader
I'm facing a problem with Link2SD app, when I try to make a link ( any google playstore and APKs ) I got This error:
-----------------------
Failure
Link2SD package invalid
-----------------------
but all the other features of the app run correctly, I have read before something that might be the responsible for the error but I didn't totally understand it , that the directory where I'm trying to make the link might be changed to be ~ read only ~
So, Please I need any help and I'll be grateful.
