Ok then. Would anything happen if I imported DNS to BTS at this point or should I wait?
And lastly, should or can I send PlayBTS_S1 and Dec.14,2014BTS_S2 from BTER to Bitshares client?
glad to see you recovered your funds. i would recommend getting a computer to use exclusively for crypto and nothing else. I would also recommend making backups of all your wallets and emailing them to yourself, backing them up on dropbox, burn some cds and scatter at friends and relatives, make a micro-sd card, maybe a couple flashdrives, copy them to your phone, etc... I've given myself a million and a half ways to get access to a backup wallet anytime i need it. your level of paranoia should probably correlate with the amount of money you have invested.
the transaction scanning can take a good minute.
the bts you got awarded from the merger snapshot wouldn't be showing up yet, you can check it with wallet_check_sharedrop (or something like that) after importing all your keys (DNS included I believe). sounds like your balance is correct.
PlayBTS_S1 is just bter's record of what they owe you from the snapshot when play comes live. it's not possible to withdraw it yet.
