Ive been buying and downloading Guitarist for a year or so. The software got an - ahem - "upgrade" a couple of months ago, whereupon I lost all the purchased mags. Ive tried following all the instructions for restoring lost editions, but it doesnt work. Ive tried contacting them three times, and all three times Ive received a useless automated reply. I give up. The App doesnt work, and obviously they have no idea about Customer Service. Pathetic.
