Hello so here is how i got in the PTR 1.0.5 Servers
I did get Error 12 every time i tried to log in, after i did that i got error 3005 so i just try spamming my way in and boom i got in, because the servers were full or stuff like that so don't give out till u test it!
P.S. I'm From EU
1)Open normal 1.0.4 game client.
2)Change Region to Americas before logging.
3)Log into Americas
4)Create hero there.
6)Change region back to Europe.
8)Exit 1.0.4 game client.
9)Open 1.0.5 PTR game client.
A) You didn't Create a PTR Account and B)Try Changing your Account Password to Sync the accounts.And Error 3005 is an Error that's Preventing the Servers from Crashing from too many ppl connecting at 1 time that's why you need to try and get in (by spamming it like i did) it can take u some time (for me 20 mins).
