I'm not familiar with this specific MYR wallet, but I did some digging and it looks like a custom private key is required for it. Has anyone else been able to set it up or is anyone willing to share their private key for reference?
I'm not sure what's going on here, but the character limit for a private message has been increased to 2048 chars for a long time now. Can someone translate the Russian text, not all of us are fluent in it.
