ChekaZ,
I swapped out the old wallet for the new one but the new one isn't finding my old wallet data. I know it rebuilt the chain but did it completely wipe out my dat info as well? I backed up the old wallet prior to the switch, do I have to drag that back to the appdata folder?
I'm sorry if this is a stupid question in advance.
Based on my understanding of what you did, I would imagine you need to have the wallet(s) closed and copy the old one's data folder to the new location (/Data location changed to "%appdata%/TrezarCoin"). If I misunderstood, please feel free to clarify.
As always, please keep careful backups.
Good luck!
