2 accounts in 1 house

[OuterChimp]

So, I got p1999 on my son's computer. We have his account up and running but it won't let me be on at the same time as it says the ip is banned - I'm assuming because we are both on the same ip? (we use the same wifi).

I tried the search function and can't find anything.

Any insight or some guidance on where to look to rectify this?

Thanks.
