ch 5 lesson download crashing

Hello,

I completed chapters 1-4 lessons in the syntorial v2 app, and was prompted to purchase the app before i could continue. I upgraded my membership through the app, and then proceeded to open the first lesson of chapter 5. A window came up saying I do not have that lesson downloaded, and it prompted me to download them. when i click the “download lesson packs…’ option in the menu, the app just closes out and nothing happens. I tried reinstalling the app, but the same thing is happening. I sent a message through the contact support, but wanted to post here as well just in case. I have not tried downloading the mac version, but Id really like to use the ipad app since it is the most convenient way for me to use syntorial.

thank you for the great program, love it so far and hope to continue my lessons.

cheers
