I found out the site was not for my bitcoin wallet i have bitcoin core
Best regards Nick
you did say bitcoin core on your first post then posted multibit.org link, and I failed to digest the info
anyway, your tx dated 2018-01-06 and cannot be seen on other explorers now, dropped by network
so if it is still unavailable in your wallet, then try right click on the tx and choose abandon
if it is greyed out, then your next try is to restart your bitcoin core with parameter -zapwallettxes=1
hopefully it would show your balance back in your wallet and then you can create a new transaction
