bitshares community,

Things I have:
a) a wallet.dat from the first bitshares bitcoin-style program.
b) the chain torrent downloaded

ISSUE:
I cannot import the wallet.dat

getinfo command reads:

>> getinfo

{
  "blockchain_head_block_num": 3832292,
  "blockchain_head_block_age": "1 years 8 months old",
  "blockchain_head_block_timestamp": "2015-10-25T11:40:50",
  "blockchain_head_block_id": "b46d7568e4ae99314919c540ab63b105d706b2ae",

however when I execute the import command, I get this error:

wallet_import_bitcoin G:/Coins/bitshares-pts/wallet.dat PASSWORD test2

13 class DbException: Db::open: Invalid argument
Db::open: Invalid argument:
    {"what":"Db::open: Invalid argument"}
    bitshares  bitcoin.cpp:338 bts::bitcoin::import_bitcoin_wallet

    {"wallet_dat":"G:/Coins/bitshares-pts/wallet.dat","account_name":"test2"}
    bitshares  bitcoin.cpp:32 bts::wallet::wallet::import_bitcoin_wallet

    {}
    bitshares  common_api_client.cpp:3037 bts::rpc_stubs::common_api_client::wallet_import_bitcoin

    {"command":"wallet_import_bitcoin"}
    bitshares  cli.cpp:626 bts::cli::detail::cli_impl::execute_command

in addition, the bitshares program seems to be blocking me from creating a regular account due to:

The wallet needs to be fully synchronized with the blockchain in order to create an account. Please be patient.

any and all help would be appreciated.
