CannabisCoin CANN paper wallet wont sweep or export..starts with 6F

hey guys... hope someone can help me.. yes i'm new to this all.

Re: CannabisCoin (CANN)

I like the Cannabis stocks off the crypto arena so I started off grabbing some of these coins and also to learn with, inexpensive!

I used the Online CANN paper wallet generator as found it in a post (same as walletGenerator, but had list to choose from for Altcoins): https://bitcointalk.org/index.php?topic=827998.0
and moved things off Bittrex to the paper wallet fine.
searched and see two of the three transactions of mine on https://chainz.cryptoid.info/cann/tx.dws?3004662.htm

the 1st public address being:

CQYc3bwvgA3npdLfFYkR9duvA2KcEfgmGH
2nd:
CSoxP7Ph9C6nnFdDZ199WPM8iR5bp2gBRA
3rd:
CS8WPNS4xCuVBHNQRAPqbS6ryGLNMZuRkT

All shows everything there fine, input and amount..

problem is how do I export it back to Bittrex? i tried sweep with few programs but get invalid.

The Private key for this one and all the three paper ones I did start with 6F, and 6E
I read about encryption and stuff with invalid Private keys but I cant seen to figure this out....

What am I missing or what is the step by step process in sorting this out?

I would love some help to sort this out before I just call it GONE..

Thanks so much everyone, I tried to read and figure this out but just coming up empty.
