Great, glad to hear you got it sorted out. The fees are very important, and it's only a very small amount (.0005 BTC or .0001 BTC) so it's definitely worth paying them. Regarding the portable version, everything that it needs is stored on the USB stick so you PC crashing wouldn't effect your BTC as long as you have it all stored on that wallet. If you're concerned about your PC crashing though, the string of words (the Wallet Seed) that it shows you when you're first setting up is what is used to restore your wallet so don't lost access to that! Make sure you have it written down / saved somewhere safe and secure. If you ever need to restore, feel free to message me and I'll walk you through it. Libertas
