Working on seeing what's going on with 2.0.0.5 because some people have issues, and some don't.
Hang on tight with us, in the meantime you can use 3 and 4 just fine.
It seems to be only people running linux for the masternode have problems.
Windows masternodes and windows controller wallets seem to be fine, judging from the replies on this thread
That is my case. I am running 2.0.0.4 linux masternode on VPS with Windows controller using 2.0.0.5. Couldn't get 2.0.0.5 to work for linux masternode. Didn't try Windows masternode + Windows controller both using 2.0.0.5.
