Hi all, I have been trying to download Mountain Lion from App Store without success. I have the following message appear: "We could not complete your purchase. The product distribution file could not be verified. It may be damaged or was not signed." This also happens on my wife's Mac Book. I am using Virgin Media provider (30MB) through Virgin modem hub and Apple time capsule. Have tried disabling anti virus - no change. Have tried by-passing time capsule and direct into iMac - no change. Apple support are trying to resolve issue, but I thought I would ask on Forum if anyone had any ideas on how to solve issue. Apple say my iMac and Mac Book are both running correct OSX.
