Debug.log file was pretty huge. Deleted it, then restarted wallet with the -zapwallettxes=1 flag, then created a new transaction. This is using version 2.4.5. - Let me know if this info suffices, or you need more from the debug.log file. It nearly instantly grew to 8MB in size.

Okay so now I deleted all files in my appdata/roaming folder except for wallet.dat and masternode.conf - ran the deinstaller, then reinstalled. Do I now have to start the wallet with the -zapwallettxes=1 flag ? Or just try sending a transaction again?
