i have amplitube 2, live, metal and fender and i use an m-audio usb bus powered interface to plug in and when i open up ant of them it says that my sample rate isn’t supported by my interface, check sync stuff in control panel or somethin like that. i got em all yesterday and they work fine. but i tried using them today after i got home from school and nothin! so i reinstalled the drivers and tried all of em and they worked till i tried the last one then it started doing it agian. i swear these are the full versions, help. i need these for my band cuz our amps suck :p
