What happens if you have an old wallet version 0.15. Can you update to the latest wallet?
I have downloaded this odarham wallet also and have to say it is the worst piece of software I have ever used in my life.I have old legacy wallets from 2011 that fire up and sync without any problems but this pile of garbage literally hogs my whole operating systems resources trying to get it to run.It will not even open saying it is replaying blocks and remains at 0% for hours on end.It started once and then got stuck processing blocks for over 10 hours until I finally gave up and when I tried to start it again it wont open with this replaying blocks shit.The piece of shit wont even shut down properly without having to use task manager to close the programme.I wouldnt risk using my wallet .dat in this junk or you might lose your coins if you are coming from an old wallet like person above because they have literally destroyed BTX fucking about with new algo and taking a wallet that worked fine and turning it into what is literally something worse than the spawn of both malware and a virus. PIECE OF SHIT
