i don't need to problem was solved the question is why it was solved that way and way this problem occured :p thanks for helping

If your folder location changed, your app possibly couldn't find the new location. Running the update may have cleared the cache and allowed the app to figure out where the new directory location was. If you didn't have debugging set to true perhaps you got a blank screen rather than an error which would have pointed you in the right direction?
