I'm trying to upgrade the firmware on my cube 2 and I'm having a problem. I downloaded the upgrade tool when I hit the "check new version" tab it says "check new version". I don't know what I'm doing wrong. I properly unzipped the install tool and got the mod connected properly... windows installed the driver. Also I am holding the fire key down the whole (like smok says), some of the time, or not at all! Nothing chages... wtf?
