Hello, I have an XTS 5000, the current codeplug says the model number is for a model 3 (H18UCF9PW7AN), the codeplug I've written says the model number should be for model 2 (H18UCF9PW6AN)...I get an error message that model doesnt match, and it won't write thee new plug, any idea how to fix this.......thanks in advance
