Having two URU capable computers and kids, I created a second account so they could play together.
The account usernames are Tony and Tony2. Too similar???
I get the first computer on DI and playing normally. After logging into DI on the second computer, the first computer locks up at the next link.

Both computers are running XP Home fully up to date. I am using a 4 port DSL router gateway provided by my ISP, (Verizon). These computers and router work correctly for simultaneous use of MOULa.
I used a clean install of URU CC for the first computer, then patched it for DI and it ran successfully. Since the instructions I read implied that URU does not require any registry entries to run, I copied the URU folder from the first computer to the second. Both computers run DI fine on either account until I try to run both at the same time.

It is my guess that the server or comm network think the two accounts are one and the same although I correctly see the different explorer names on the two accounts when used separately.
I have tried to provide as much info as I can, please ask any questions.
Edited 1 time to correct a typo.
