This sounds like an issue with your flash drive! None of our PDFs have any security/encryption that would prevent you from opening them. Have you tried emailing them to your father's email?
What kind of issues are you getting? There's a thread here that might help you:

I alternate between Google Chrome and Firefox but I find Firefox is better for 7sage. It seems to be working fine for me, so perhaps it can be your internet connection. Make sure your flash is up to date as well. =)
I feel that the easiest way to memorize these forms is to actually make flash cards and go over them a couple of times. I did this about 5 times in a row & I was able to recognized all valid & invalid forms afterwards.
Oh goodness. I saved all the PTs to my computer last night, already have Cambridge saved. I'm almost done saving everything to my flash drive. Fun times.
@emli1000 did you buy all the PTs that don't come with the ultimate package? I want to get them before the 7Sage license runs out (April 24th), but I want to make sure there won't be a flash sale due to the circumstances >.
Ahhh really? they used to let people view the flash cards without having to make an acct :/ if you want you could make an acct lol it's kind of useful ... if not i could send you my notes on arg. forms.
Yeah I watched EVERY video in the curriculum at increased speed. Not sure why you are not seeing it. For LG, I had to switch to the 7Sage video player, but the button was right there.
Seriously thank you for posting this !! I have been wanting to make flash cards containing info like this for awhile now, but haven't gotten around to it. You sir just made my life a lot easier.
