aif samples from Live packs don't play due to license?

Hi Experts,

I building a simple sample launch instrument max patch.
I noticed that I could play (sfplay) certain samples but others I got a "can't open aiff file" error.
After hours of debugging and noticing these are files from Ableton Live Packs I suspect that these are license protected samples.

Is there anyway to play these samples in my max plugin anyhow?
How is that license management work can I inherit the license into my max plugin?
Thanks.
S
