glad you got it fixed, however, your old multibit did pick a fee of < 15 sat/byte, while at the time of writing a fee of 510 sat/byte would be recommanded if you wanted to have a 95% chance of getting into one of the next 3 blocks (source: https://bitcoinfees.21.co/)

You can be lucky and see your transaction end up in a block in several hours/days, but don't be supprised if it stays in the node's mempool untill they decide to drop it...

I'd personally recommend to use the viabtc txaccelerator: https://pool.viabtc.com/tools/txaccelerator/ (read their full FAQ/TOS before using them, or you will probably won't be able to submit your tx due to the fact they only accept a certain amount of tx's per hour)
