i think baikal miner is a big scam, but its a long term scam that's why, a lot of people be deceived in it.
How? They sold you hardware and you received it as promised...
You think Baikal is the only company that "promises" something and then underdelivers? How about Samsung, apple etc?
This thread is getting way too boring and with only useless comments from useless trolls.
There used to be actually good info here.
About your problem, if your XVG wallet doesn't sync, try to download the nightly shapshot:

You will find the whole blockchain.
Backup your wallet, close qt, download and install that archive, restore your wallet (if needed, if you didn't delete wallet.dat you could skip this step) and you should be ok.
At least, it worked for me.
Good luck. :-)
