Thank you for your help, I have already visited these two links and it does tell you how to reset the user code, I have followed these instructions but have not been able to change the code. The code I want to put in is my old user code, it will not let me put this in, BUT I have found out if I use another code like 2222 or 3333 I can input this new code, I cannot understand why I cannot input my old code, anyone any ideas?
