BNet launcher issues

(Using ISBoxer) I got a 5-box WoW group going through direct launching so I've been now trying to get it to work through the launcher for login convenience. However, each time a session launches the Launcher tries to do a small update to it (I'm not sure if it even downloads anything), which fails on sessions 2-5 due to files being in use. The launcher also does not seem to display the correct subaccount preselected.

This is what I did:

1. Created a new IS profile for WoW w/ Launcher:

Main executable filename: World of Warcraft Launcher.exe
Main executable parameters: NULL
Main executable path: G:\Games\World of Warcraft
(The next 3 Launch without entries are blank)
Monitor selection: Application controlled
[ ] Force Windowed

2. Changed the characters in my set to use this new profile
3. Made sure all characters have virtual files for: Config.WTF, Battle.net.config, Software/Blizzard Entertainment/Battle.net/
4. Exported to ISBoxer (several times)
5. Launched them all and logged into each one in turn and selected the correct sub-account
