Every time I attempt to logon I get the following:
"Unable to validate game version. This may be caused by file corruption or the interference of another program. Please visit {blah blah some blizzard link} for more information and possible solutions to this issue."
I found some other threads about this issue but nothing has worked and I am unable to play.
Let me guess, you play on Macbook / iMac? Same problem for everyone on OsX. The problem is temper, it can last from few hours up to few days. All we have to do is just wait.
