Came across your thread regarding the remote app patch. I hope that fixes the issue but i am not able to download the zip. When i click the link it downloads the folder. I have also attempted to zip it myself but the message i get after trying to apply that patch is "e footer is wrong, e signature verification failed".
2nd issue is that i have also tried to register to your site but i am not getting a confirmation email. You might have a different link on your site.
