Also as for development price and general slowness, as munti said I had to take care of things in my personal life. Crypto is my full time job right now so don't worry. I'm still working on completing Bitbay (including the pegging). It should be noted that we already have decentralized markets one year ahead of open bazaar.
As for crypto in general, not even bitcoin has hit main stream yet. So people are not focused on the utility of crypto yet we are still very early in the space.
Thought wallet was not connecting because the blockchain was down, but if you have another 1, don't think the wallet connects to that chain. Love the Bitbay project and think this the future of online trading. Sadly since my Hard drive broke, can't seem to get wallet back online for staking or anything else for that matter. Maybe I have wrong wallet version, mine is 1.0.0.1, is there a new wallet version out? Your link for wallet from Dec 20 does not work.
The blockchain is fine. Looks like you found yourself a very old link. Try using the link in OP or at our site http://bitbay.market/downloads/
Let me know if that fixes it.
Edit: You said you have other wallets running. Could be a port conflict also. Read up here how to change port: http://bitbay.market/forums/topic/running-qt-and-client-simultaneously/
I wiped the hidden files and removed old qt wallet and downloaded the 1 you suggested with same results. Shows 0 active connections.
