Your issue sounds different. It sounds like you might have your wallet.dat, but you are somehow either connecting to the wrong network or the block history your wallet is very old/invalid and isn’t part of the current network.
I suggest that you backup these files (wallet.dat, syscoin.conf, masternode.conf) to a thumb-drive or similar. Those files can be found in the Syscoin data directory. Here is a guide for locating that based on your system/OS:
Then delete everything in your Syscoin data directory, copy the backed-up files back into there. Then attempt to reinstall Syscoin 4.1.3 fresh and let us know how that goes. Once you open the freshly installed wallet it will begin downloading the blockchain again (this will take some time). If the issue persists after this we’ll be happy to help further, but that should solve it.
