Fewer than 1% of people involved in cryptocurrency are women.

Warning! Warning!

I spent many hours trying to figure out my mining problem only to discover after talking to the Satechi Technician that Satechi hubs are not recommended for use with ASICminers USB Block Erupters. The company doesn't recommend their hubs for mining. Appears to be a serious lack of power, even with their powered hub.

First of all your using a uncommon wallet, and it might be a heavy wallet.
All wallets contain a copy of the blockchain which is essential for the bitcoin network to run.
The 'blocks of transaction' might be your version of the blockchain.
Currently Blockchain is ~13Gb so I would recommend you to use a light wallet such as Multibit, these wallets are secure and doesn't take up as much space as the Blackcoin wallet you're using.
Your better off using the more common wallets: https://bitcoin.org/en/choose-your-wallet.
Don't use web based wallets because they can be hacked.
To back up your wallet you just have to export it to a preferably safe location
Import a wallet to utilize it after you've export it
Good luck 
BTW the first wallet startup is always the longest
