you know this really is not that difficult dude,
i don’t understand why you delete your dice servers folder (or rename it, or whatever you did)
first thing first: uninstall triplea, and then reinstall it
second thing, read what the help button says
all of the answer’s I’ve given you are things you could have figured out by reading the help documents included with triplea
third, when you register your email with triplea war club dice server, it will SEND you an email. you have to click the link in that email to finish the process
if you need further help, please read one of these tutorials:
