I'm new here on this Board. I bought the Beginners Course and the Songs Book as well.
I also Paid for the Practical Music Theory and downloaded that File. Today I tried to open this Book on my iMac (El Capitan) but wasn't able to. It seems to be damaged or a false file-format. I tried open It with Preview ans iBook.
Can I redownload It? Or what can I do?
Greetings and thanks for the excellent work so far. I'm making big pregresses
