I was trying to setup desire masternode and i have used https://www.youtube.com/watch?v=YX5KXeU7P0g&t=96s   link as guide. As per video 9.53min, i opened and changed  wallet config-masternode config . Then i saved and closed notepad. Accidentally i closed wallet as well. After that i was not able to open wallet again . I have 1000 desire in it. Can someone help me to fix this problem and help me to setup masternode?
