I lost my game hours in Xfire, I don't know this is only temporarily or what, but I hope it will be fixed and I got my game hours again
Go check your Xfire profiles to see if you got same problems
And go check xfire forums at technical support board, apparently a lot of people/players also lost their ingame time/hours
Here is the link to Xfire's forums
