Running Steam GUI under CrossOver 6.2.0 on SuSE 10.1
Opening downloaded games has been failing every time with "game is currently unavailable", so I removed Steam and re-installed it in a new bottle.
After the "Steam Updating" dialog reached 100%, wine displayed "Steam.exe (main exception): Unable to start Steam Engine: ... The registry is in use by another process, timeout expired." After OK, I was able to launch Steam anyway and login, but every install request says "The Steam servers are currently too busy to handle your request."
Random info:
(1) The Steam servers were not too busy to play on my Windows machine.
(2) chattr +D ~/.cxoffice/SteamBottle/drive_c/Program\ Files/Steam/ yielded "Inappropriate ioctl for device while reading flags on Steam"
(3) Troubles coincided with messy installation of ATI video card.
