I realize this is a old thread, but I just got Isboxer and trying to get it to work with Warhammer online. I have 4 different Warhammer folders and I can run 4 accounts at the same time using each of these. However, when I try to launch it with Inner space, it will launch the launcher, but when I click play it will give the error " Failed to startup streaming - Please re-launch Warhammer Online " ...
All clients (both the patcher and war.exe) are running under administrator. I also watched video's on how to setup Isboxer, then exported it to Inner Space.
Windows 7 x64 Ulimate
6 gigs of ram
AMD Phenom Quad 9500
GeForce 250GTX Video Card
As stated before, I can run 4 clients without Inner space just fine using all 4 warhammer folders.
I would appreciate any help with this! Ty!
