Yeah... I'm not about to read 500 lines of code.

Are you getting errors? What are the errors? Which lines cause the errors?

Are you not getting errors but it's not behaving in the way you expect? Which lines of code is executing incorrectly? What behavior is resulting? What is supposed to happen instead?

no im not getting errors. it runs fine but it wont create the encryption file and save the password from the textBox2.text and encrypt the password and then when the user types the same password in again it doesn't recognize it and cant decrypt. and I created a fail catch point to recreate the whole thing but it doesn't want to work. and I've tried everything

Like I said earlier, I'm not trying to read 500 lines of code to find the one you're talking about. Please tell me which block of code it is and which line number you're referring to.
