Windows 7, 64 bit. the new wallet crashes once it launches. Any ideas? Is there an older version I can use?
you can try the 32bit version, I run win7_64bit, run the 64bit client, on 3 different systems
https://dl.dropboxusercontent.com/u/107300/fluttercoin-v0.4.5.10.zipcheck your %appdata%\fluttercoin\debug.log file and see if there's anything that indicates why it crashed.
This version does not work for me, upgraded and boom! don't work!
Mac version still works tho.

soomster you still on 4.5.7? or you are not in sync, come on you can do better...you can use this to sync if you have to.
rpcuser=x
rpcpassword=x
rpcallowip=127.0.0.1
noirc=1
listen=1
dnsseed=1
server=1
connect=54.215.241.255

connect=54.84.46.196
just remove connect statements after you are synced up so you can find other clients on the network
And stop spreading fud, look a the network tab on explorer, 45+ nodes right now on it. If you are having issues, send a PM, or provide debug.log output so we can look at it. Usually a good reason it's not working for you, and that checkpoint error, means you are not in sync.
