I saved a copy of the hidden .navcoin2 folder in Ubuntu. Deleted everything, made new 3.7 wallet and just copied the .navcoin2 files back into the new made .navoin2 folder replacing them except for navcoin.conf where I used your nodes and settings.

I just made up a random rpc name and password (that's ok right?)

Now I have one connection to the network and all my coins are back so it must have worked, am I correct doing what I did?

Only problem is my network weight is about 1000 NAV off my balance in my wallet and I'm not staking just yet, which now I think is probably an old stake not matured yet. I'll wait and see.
