tried blank too..
fuck !!
problem is, there is no password to remember. At no point in setting up my account did I create a private key pass or a second password. I have just the main one which I can log in fine with but is not recognised when trying to decrypt my private key

((
what a headache !!
edit. either i forgot my old strongcoin passwords, or this is another bug in their system. it is possible their server is overloaded(site seems pretty slow) and the requests are failing to process. also the client could be down on their server. send an email to support about it.
