I have a problem whenever I download a newer version of Toribash; Namely, I lose my old account. I had an account I created on a pre-3.72 version, MrQwerty. However, when I try to log in as MrQwerty on 3.72, it says 'error: failed writing recieved data to disk/app...' I can't read the rest of the message because of the white in the background. However, I haven't typed in the wrong password because I click show, and it's not misspelled. To make sure I'm thinking of the right pass, I check on here, and it works. However, I downloaded the 3.8 beta, and now the same thing happens to this account; It won't allow me to log in. Any ideas?

Hmm, have you tried changing the password?
To do so, go here.

Well, it's not a password problem, seeing as I used the same password for this account, thinking I'd not need it for long :/

Yea, but if you change your password, your account will be updated, and you might have access in game again, tough thats just a rough try.

Did you try editing your tb_login.dat in your Toribash folder?
That contains your username and password.

Open tb_login.dat with notepad and you will able to see your login data.
Also make sure you write will correct order (No uppercase or caplock)
