This version of wallet SHOULD ACCEPT wallet.dat. Maybe you placed it in a different folder? Have you tried asking for help in their Discord Channel. They're quite active there. Link's below.
The folder is only ONE on the PC, it is not possible to place anywhere else.
You get away from answering the questions, WHY FORK? What is wrong with the original version? It works great and brings stacking.
There is no website, there are no developers, the project has no purpose, trading on exchanges is zero. Coin value 0 Satosh.
Why all these movements with wallets and riveting new versions every month?
Discord is not popular now, everyone has gone to Telegram, it is convenient, safe and fast.
P.S. Please do not hang on to these forks. Because why put dubious software on a PC, the answer is not given. As there are no answers to the above questions.
