can a simple "checklist" or bulletpoints be posted as to whats going on and How-To for the new wallet?

If im passed the illegal TX i need to run reindex=1? Whats the illegal TX/block numbers?

I just downloaded and ran the new wallet and let it run for like 10 minutes and its stuck at 99.9% and I was synced to like last 48 hours or so when I got a payout. so its pretty recent/assuming im synced past the glitch with the last version wallet.

Do I have to create the guncoin.conf file and add i reindex=1?
