On July 12, 2007, Dusty Welch of RedOctane stated that there have been over 300,000 downloads of the music packs until that point and that the prices were "very attractive and desirable for consumers." On September 11, 2007, Activision reported that with over 650,000 downloads, the music packs qualified as "multi-platinum" under RIAA's definitions. Technical issues No official statement from RedOctane or Activision were made about the discs or the game itself having any issues, but players have reported songs freezing or skipping, causing the audio to be unsynchronized; unusually long loading screens; and menus that freeze or lock up entirely causing the game to crash. The RedOctane Support Center Answer Guide states, "We’re already in the process of looking into this and testing to replicate the experience. We’ll notify everyone with our results shortly, and will have a positive resolution if need be." Two models of the X-Plorer controller were released for the Xbox 360 version of the game: model numbers 95055 and 95065. Of the two versions, the 95055 has an RJ-11 jack for effect pedals near the controller cord and is subject to having an unresponsive whammy bar. RedOctane later responded, saying that they "isolated this issue to two model numbers that can be found on the guitar's packaging". Customers are able to exchange these models for new models. On April 13, 2007, Activision revealed that the issue was not a problem with the hardware, and that the guitars were not'' defective. The cause of the problem was anti-cheat protection software, and Activision released a patch on Xbox Live on April 14, 2007, to remedy it. However, this patch may have caused some unintended side effects. Starting on April 16, 2007, numerous users began reporting lockups and failures of their system after downloading and installing this patch. RedOctane stated, "We're aware of the problem and we're looking into it." Numerous game players have also reported problems
