HI, I bought the IOS version for ipad. I‘ve been playing for many months, and then I uninstalled the game. I reinstalled it back recently (using it with the same GameCenter account), but I can no longer choose the song I wanna play in the « Play » menu (it’s ok for the « live » menu). When I try to do so, i get the message that I should « buy » some guitar hero cash (or something like that). I paid 60$ for thi app and, being so overwelmingly expansive, I cannot understand why I should invest more cash to use the function I always used in the past (before the uninstall / reinstall). What should I do? Thanks for your concerns.
