Why don't you get the 1.0.6.1?

If you have a legal copy thru Steam, you should be able to automatically update.

If you haven't, well, I don't want to advertise piracy but you can get an updated version (1.0.6.1), too. I have friends who have "non-steam" version Terraria with 1.0.6.1 and they can play on the same server, where I play with my legal copy.

But, please, If you like Terraria and like playing it, buy it and show your support to the developers! Its $9.99 :)
