If you post the transaction's ID here the community might be able to help.

Very old versions of multibit were capable of sending transactions that included something called high s values. Since then the Bitcoin network has been changed yo only accept transactions with low s values. If your wallet sent a high s value transaction the network will reject it.

Upgrading to the latest multibit classic version will solve that problem

There is a problem with Multibit Classic where the transactions with high "S" values are not accepted since the Bitcoin protocol is now enforcing low S values only. So my question is will the developers and maintainers of Multibit upgrade classic to use only low S values when sending Bitcoins?

I hope they will since I like the classic wallet better than HD. I would hate to run into problems where my transactions would not be accepted by the network.

Besides that problem the network has a high backlog of transactions. Any transaction without a very high fee per KB is likely to take longer than normal to confirm.

OK thanks, I will wait until tomorrow morning then I will move the funds through a new multibit version or an other client. The size of the transaction is 18,687 bytes.
