unknow expiration date act now

Put the summary of the bug you're having here

*What I expected to happen was...:
well i had a account that was called coolingwalter16
a while ago and i tried to open the launcher and it failed

What actually happened was...:
my account was turned into a demo account dont know how don't know why and i have a new account called coolingwalter which when i got it
i thought that was very strange because when i had my original account
had every username taken up to the number 16 so i had feeling that other people lost there accounts as well so i look in the code and found a expiration date hidden in your code but right next to my user name
so i didn't mess with it and i contact support help and handed them the file that i found it in they said there was nothing wrong with my acount but i still see the expiration date to this day and i checking again to make sure
and ....... it still there at the time of this post the date says 2016 9 19
wich is backwards which means 9 19 2016 and its in the usercache config file open it up in note pad it will give you the expiration date and the computer says it is a json file and thats where you will find it
