I'll be firing up my masternodes tonight now I'm back home. Will probably delete and resync them all too just to be on the safe side.
A couple of mine had the errors, but went ahead and did that to all of them. Looks pretty solid so far.
Mine darkcoind booted, took his time (2min 100% cpu @ raspberry pi2) and killed himself. This morning i recompiled it from github and deleted all except darkcoin.conf. When i get home i will try a new fresh start. Il will let it generate all the necessary files. I hope it will fire up and stay up.
