Try Deleting Settings file in Document/X Comic Downloader and delete every thing that are in it, then run the app again
how can i update?
you can go to settings, scroll down, there is a button called Check Update, press it, it will check if there is a newer version available or not, if it is available then some thing down mid of the screen will pop-up and you can press update there.
it didn't work but thank you
