Check point warning is longstanding annoyance, but doesn't seem to interfere with functionality. Version 1.5.2 is not syncing for me too, the older QT is.
i'm trying the 1.5.2 ver also - up to yesterday 5:pm blk # 337907 sf ...
can you share you conf? peer? I can't seem to sync...
addnode=0.talk.bitnodes.net
that should be all you need
BUT i think the problem is
bitnodes(that explorer is only at mid June)
http://explorer.cryptoblox.com/chain/BTCTalkCointhat chain is up to date / perhaps idle waiting for a block to mint
but i have no idea on their node
(sorry i've been sending emails for months asking)
if anyone can get us our 'old' blockchain @
http://www.multifaucet.tkback I will bounty both you and GrinZ (the site op).
also willing to fill the faucet there too.
multi is a good back up as they also post the network nodes/peers
maybe this can help. couldn't connect at all with the bcc wallet. i'm still up to 'yesterday @ 5:pm'
