I am running pro tools LE7.3 with an MBOX2 mini on my macbook.
Pro tools has been running fine, however when i last tried to open the program, Pro Tools had changed to the Japanese version and requiring me to change my finder to Japanese. Both the computer and Pro Tools were bought in England. How can I change it back??
