Please give me advice! From about 4 to 5 months I have a working masternode under Windows. Since the new 16.1 wallet is installed, I can not run the masternode. If the masternode=0 in the chaincoin.conf file, the wallet is loaded and running normally, but if I put masternode=0, the wallet does not want to load and every time show this message  "You need to rebuild the database using -reindex to change -txindex." This is my full chaincoin.conf file.
-- chaincoin.conf --
rpcuser=*************
rpcpassword=******************
rpcport=11995
rpcallowip=127.0.0.1
logtimestamps=1
daemon=1
server=1
listen=1
masternode=1
mnconflock=0
externalip=***.***.***.***
bind=Local IP
maxconnections=256
masternodeaddr=External IP:11994
masternodeprivkey=*************************************

Note: I've already tested Sentinel for Windows from Innovacoin masternode and I think it will work well.
Any ideas where am I wrong?
