I bought some bitcoin back in 2013 and transferred it to my private wallet managed by MultiBit classic 0.5.17. I have successfully used the system and spent some of the funds in MultiBit Classic as recently as July 2016. Everything worked flawlessly up until that point.
Now I (and I imagine many others) find myself in a tricky situation. MultiBit classic does not allow for transaction fee adjustments and has a hard-coded 0.0001BTC transaction fee. Currently this is about an order of magnitude too low for any transaction generated with such a fee to move along. I know this because I have three transactions stuck in "unconfirmed" state for over a week now. I have tried to migrate the funds to a different wallet, but so far have had no success. MultiBit HD, the replacement for classic does not import secret keys. I also tried Electrum, but that only imports secret key into a "watch only" wallet, so I can't spend any funds from it. I am still looking and trying, but am getting really exasperated. If anyone knows of a way to transfer my bitcoin held in MultiBit Classic 0.5.17 into a modern wallet where I can set transaction fees so that I can move transactions along, please let me know.
