"Error: A fatal internal erro occurred, see debug.log for details"

On my start up from a week away after setting up two masternodes, Syscoin Core gives me the error when starting up. I then immediately closes. I cannot get to the debug file, I cannot open Syscoin Core at all now. How do I alleviate this error without losing my two wallets containing a master node each. It worked fine setting them up, now, this error. Thank you for the help,
