user42293: I am using Multibit HD 0.4.1. I was trying to send 0.5 bitcoin, but it seems to be unconfirmed for an hour.
I tried repairing my wallet, thinking that was the issue, but now my previous balance became unconfirmed! I had about $340 in my balance but now it says $0, with $340 unconfirmed. Will the balance be confirmed once the sending transaction is confirmed? This is time sensitive, so I need to resolve this issue quickly.

user42313: The other guy is wrong, I have the same problem as you( http://prntscr.com/cv38x1 - the coins were confirmed in 2015 but it shows transaction status as unknown).
Your issue is most likely the one described below:
https://github.com/keepkey/multibit-hd/issues/862
- this didn't work for me, but I recommend you try it as it did help some other people.
Now if you still have the problem, I figured out how to recover around $100 out of $146 by using the Mnemonic phrase to generate my old private keys, but for some reason it only generated some of them (I suspect that the reason I couldn't recover all of them is due to an issue with BIP32 compatibility Multibit had a year ago).
