Hi FlipPro, i am a computer engineer, i can try to find your wallet.dat.
I’m one of the developer of xdag coin and i did a lot escrows services for that coin (at least one shot worth 50k$, but a lot of 20k$ each). So i think that i’m reliable, if interested you can send me a PM and i’ll show you more references, if you need.
Cheers
Marco.
