Yes I know the solution. This happens when you got your PC "forcedly" restarted or shut-down. The solution is simple: back up your wallet.dat file from the SUB1X folder, delete the entire wallet, download again and install. After that paste your backed-up wallet.dat file and start your wallet. You might need to wait more as it will synchronize with entire chain. Also if your wallet.dat got corrupted as well (happens with me) I just used the old wallet.dat file which I backed-up like first day after synchronizing of my wallet.

PS: Back-up your wallet frequently. 

Was enjoying this coin up until the latest swap- their instructions were a bit unclear and I ended up not being able to redeem my coins. Communication doesn't really seem to be priority for the devteam and there are numerous delays with not so clear announcements or instructions. Their discord gives good support, however when it comes to getting help from actual developers, you're kind of out of luck.

The original swap was supposed to take a snapshot of coins on 1/26/18 - and any coins held on an exchange such as cryptobridge would be handled by that exchange. Since my coins had been on that exchange on the 26th, I would not have to handle the swapping myself, even though I had moved my coins off of crypto bridge on the 27th. Eventually, another update would be posted explaining some issues with the swap but that "The CryptoBridge situation remains unchanged, with all coins going through an auto swapping process. This will take place after the manual swaps have finished."

Finally, when everything is said and done I am still left without my 7.73028942 SUB1X or so. I had contacted both willdono and crypto (of cryptobridge) and been told they would reimburse me- but have not been. I have had no reply from them since the 11th of march and would suggest anyone else to maybe be a bit cautious- even someone like me who was pretty active in the discord was able to lose coins and time.

Every day I get from 0.01 to 0.03 SUB1X through staking. So I never get enough SUB1X for a master node. I think I buy some SUB1X on a stock exchange and then take care of a master class. Hopefully the value will develop positively.

Please remember that the day in which you sent those coins was on 10/2/2018 and during that time everyone was informed not to send or receive coins as there was a problem with the blockchain. Do you follow us on Discord? You are informed of all changes through there. We are all here to help you out if needed.

The project was suffering a lot of stuff during that time and I'm not surprised of some issue which might occur. However the community is very helpful and indeed become stronger. I agree with you that communication from dev side is need to be approved.

I think your case should be addressed asap. We should keep our  community growing and not loosing it.

I have 3 MNs running for approx 20 days and I managed to collect around 15 coins so far. Currently I'm thinking about setting up another node when I get 20. Community became very strong after some issues, I'm happy with that. However the marketing need to be improved in future. I think we can try to do some bounty when market recovers.
