Batboard

I could use some help with a vhf astro saber code plug. i am having problems writting to a radio. reads fine but when i try to write back to it it gives a error message.

1-What is the error message?
2-Did you try to cram in another codeplug into this radio, or did you READ the radio, make changes and write back to it?
3-Did you enable the secure feature on the radio, and not have a secure board in it?
