So I'm having what I hope is just a simple problem that is most likely user error. I've downloaded the program manager and have installed a few of the programs, but when I try to log into my Neopets account with it gives me a login failed error. I'm using a PIN on my account, but I've entered that field as well. I can't really fathom what is wrong.
I hate to be that newbie, but I've been trying for the better part of an hour to find documentation on my problem with no luck. Any suggestions?
