I run the bitshares_client now and it began replaying the blockchain. The is no promt like normal in a terminal window so I can't type "open default" and enter my password..
prompt will come after replaying the blockchain .. it will look like this

I always updated it by newly compiling it and then imported a backup. By updating do you mean update via a github command?
if you are under windows you can simply use the exe file provided in the github releases ..
otherwise you need to compile version 0.5.3 first, run it and import your wallet .. then you can checkout the latest version, recompile and start the client again
