Swapping accounts.

[Moneybucks]

I needed to swap accounts because I was on my brothers, and I asked how to do it. Someone said to delete a tractor file, which I did. Ever since the game has been acting strange, so I'm guessing thats not the way to do it.

How then can I fix the problem I've made myself and how should I really switch accounts?

You are not allowed to play on two accounts on one computer.
People could cheat by creating multiple accounts, then using them both to gain an unfair advantage (more starting cash, more buildings allowed, etc).
